Dr. Sean Lema (U. of North Carolina) is studying the desert pupfish (Cyprinodon sp.) in remote corners of Death Valley where summer temperatures reach 49C and the average annual rainfall is just 5 cm. Seven taxa of pupfish occur in Death Valley, each uniquely adapted to its particular habitat, and all exhibiting remarkable phenotypic plasticity—significant morphological and behavioral differences are evident within a couple of generations in response to small environmental changes in their unique habitats. Included in the traits that change are those that may be used to define the species. Thus, when the habitat changes, a species’ phenotypic characteristics may also change, suggesting that habitat restoration for recovery of highly plastic species must consider its affect on phenotype. As well as looking at the patterns of plasticity among pupfishes, Dr. Lema searches for insights into the mechanisms of these phenotypic changes. His experiments suggest that the pupfish’s physiology and

development change in response to slight environmental shifts and contribute to the morphological and behavioral differences he observes among fish in different habitats. The hormone, arginine vasotocin (AVT) is a neurotransmitter that modulates behavior in some fish species. Dr. Lema observed differences in neural AVT phenotype between populations of pupfish, and showed that AVT influences pupfish behavior. He then demonstrated that the AVT system in pupfish is influenced by temperature and salinity changes. Dr. Lema’s work demonstrates the necessity of preserving habitat for these endangered fish, and questions the basic concepts of assigning species. Northwest Marine Technology is proud to have a role in this fascinating study—please contact us if we can help with yours. Lema, S. C. American Scientist 96(1):28-36. Lema, S. C. & G. A. Nevitt. Hormones and Behavior 46(5):628-637. Lema, S. C. & G. A. Nevitt. J. Experimental Biology 209:3499-3509.

To measure the effect of AVT on pupfish behavior, Dr. Lema tagged one group of Amargosa pupfish with NMT’s Visible Implant Elastomer (fish with red tags) and then administered either AVT or a saline solution to them. Fish treated with AVT were less aggressive than the control fish. Photos by S. Lema

The American Fisheries Society is on the verge of creating a new unit, the Fish Habitat section. If all goes accord-ing to plan, the new Section will be approved at the Annual Meeting in Nashville next August. Until now, habitat issues have been a major thrust of several Sections, particularly the Water Quality and Fisheries Management Sections. However, there has been no Section dedicated solely to the advancement of knowledge and exchange of information on the broad scope of multidisciplinary marine, estuarine, and freshwater fish habitat issues. The nascent Fish Habitat Section will focus primarily on the physical aspects of habitat and will work closely with other Sections in advancing habitat issues. The eventual direction and foci of the new Section will, of course, evolve over time as its membership grows and participates in the building process.

Some questions that come immediately to mind are,

You mean we didn’t have a habitat Section already?

Do we really need another Section, given that Section memberships seem to be declining overall?

How will this Section relate to other Sections?

How do we go about starting a new Section?

In fact, I encountered all of these questions (and others like, “Are you nuts?”) while pitching the new Section concept at the Annual Meeting in Ottawa. The answer to the first question should be obvious by now. Given the number of enthusiastic responses I received while at Ottawa, I think the time has definitely come for a Section dedicated exclusively to habitat; both interest and need will be sufficient for a vibrant and expanding membership. A key component of the overall mission of the habitat Section will be to work hand-in-glove with others that have habitat as an important component of their interests. I will spend the remainder of this column describing how one goes about establishing a new Section of AFS. And to answer the final question above, “obviously.”

The very first step in creating a new Section is for some-one or some group of AFS members to perceive a need. In this case, I have found myself doing more and more habitat-based fisheries research and was looking for obvi-ous sources of information on habitat issues. It was time to renew my annual AFS membership, so I thought I would join the habitat Section, but discovered that there was no habitat Section. I was familiar with the habitat efforts of the Water Quality and Fisheries Management Sections, but saw no single place to go to learn more about physical habitat. Thus, I perceived a need, a selfish one perhaps, but a need

nonetheless. I queried several of my colleagues and their consensus was, “This is a good idea—why don’t YOU put one together, and we’ll join.” Fortunately, having spent six years as the AFS Constitutional Consultant, I had a pretty good idea how to go about the process. First, you must draft a petition seeking to form the new Section and get the signatures of at least 100 active AFS members. The Annual Meeting is an obvious place to do this; plus, it doesn’t hurt to spend some time explaining your ideas and thoughts to a large cross-section of the AFS leadership and Governing Board.

The second order of business is to draft a set of bylaws for the new Section. Here I worked with Gwen White, the current AFS Constitutional Consultant, who will present the new bylaws to the Governing Board for approval at its mid-year meeting in March 2009. Assuming the bylaws are approved, the next step is to draft an AFS Rules amendment, again working with the Constitutional Consultant, to be approved by the membership at the next Annual Meeting. Sections are listed by name with their objectives in the AFS Rules, which must be approved by the AFS membership at large. In addition to Governing Board and membership approvals, the new Section must obtain a minimum of 50 membership pledges from active AFS members. While all of this is taking place, a slate of temporary officers for the new Section will have been identified to serve as leaders until the Section can hold formal elections. Once the Section bylaws and AFS Rules amendment are approved and membership pledges are received, the Section becomes official as soon as its officers are notified by the AFS executive director.

While this process may seem convoluted and perhaps a little daunting to some, it has served AFS well for decades. The process works; we will soon have a new home for fish habitat. If you are interested in joining the Fish Habitat Section, please e-mail or send your pledges to Executive Director Gus Rassam, at AFS headquarters, and watch your annual dues notice for the new Section appearing after the 2009 Annual Meeting.

Officers, pro tem, for the new Fish Habitat Section are: President Joe margraf, [email protected]; President elect Kyle Hartman, [email protected]; and secretary treasurer, amanda rosenberger, [email protected].

UPdates oN roteNoNe reregistrAtion On 31 March 2007, U.S. Environmental Protection Agency (EPA) issued the Reregistration Eligibility Decision (RED), authorizing the reregistration of rotenone (EPA 738-R-07-005). The AFS Fish Management Chemicals Subcommittee (FMCS) has been working with the three registrants (called the Rotenone Task Force) and EPA for the past several years to secure the reregistration. The FMCS, EPA, and Rotenone Task Force meet in Washington, D.C., on 13 August 2008 to discuss concerns related to mitigation measures and label changes proposed by EPA to lessen risks to humans and the environment. EPA was open to considering alternatives to their proposals. FMCS provided alternative wording on key EPA mitigation issues of applicator safety, application systems, application rates, neutralization criteria, and public notification that were believed either unfeasible or unnecessary. Although two issues remain, EPA has tentatively agreed to the FMCS alternate proposals and FMCS agreed to develop a Rotenone Standard Operating Procedures (SOP) Manual provided that it is not considered labeling. FMCS met in Reno, Nevada, during the last week of October 2008 to finalize the outline of the Rotenone SOP Manual and assign teams to write the manual narrative and individual SOPs. An initial draft is expected by June 2009 with the final peer-reviewed document available by November 2009. The Rotenone SOP Manual will be available from the registrants or on-line at www.fisheries.org/units/rotenone.

trAining clAsses oN PisCiCides oFFered The EPA REDs for both rotenone and antimycin recommend that applicators

receive training on the use of piscicides. AFS is offering a week-long course on planning and executing successful projects using rotenone and antimycin. The course instructors have trained over 140 biologists since development of the training began in 2001. AFS, in conjunction with Arizona Game and Fish Department and the University of Arizona, is conducting this week-long course in Tucson from 12–16 January 2009. There are still a few seats available for the Tucson class. Due to numerous inquiries for the need for more training, AFS has scheduled another class from 18–22 May 2009 in Logan, Utah, in conjunction with Utah State University. For more information on either class offering, contact Brian Finlayson ([email protected]) or Don Skaar ([email protected]). Applications are available through Shawn Johnston ([email protected]) at AFS (301/897-8616 ext. 230) or online at www.fisheries.org (click on AFS Task Force on Fisheries Chemicals Course in the home page).

CHesaPeaKe bLUe Crab disaster FUnding NOAA’s Fisheries Service today announced that the states of Maryland and Virginia will each be eligible for up to $10 million to assist watermen who have been economically hurt by the commercial fishery failure in the soft shell and peeler blue crab fishery in Chesapeake Bay.

“Watermen and their families have been hard hit by a 41% decline in the soft shell and peeler crab fishery since the late 1990s,” said Jim Balsiger, acting NOAA assistant administra-tor for NOAA’s Fisheries Service. “We’re pleased the governors said they would like to use federal aid to restore important blue crab habitat and to create more diverse economic opportunities for watermen, possibly in aquaculture.” Balsinger added, “We applaud their idea to use some aid to employ crab fishermen to retrieve lost or abandoned crab pots that continue to capture fish and crabs, doing long-term damage to the fishery.”

The states will now submit plans to NOAA’s Fisheries Service outlining how the funds will be used.

eUroPeAn Union Agrees to toUgher Protection oF tUnA stoCKs

EU fisheries ministers stopped short of calling for an all-out fishing ban, but did call to step up protection of dwin-dling European bluefin tuna stocks and fight illegal fishing in November. The ministers have called on the European Commission to push for a series of mea-sures at a key international meeting on tuna, which are particularly threatened in the Mediterranean. They are also ready to accept a shorter fishing season as well as stepped-up controls all along the process, from fishing to fattening in cages to bringing the fish to market.

Both France and Italy opposed a mid-June decision by the European Commission that ordered a halt to industrial fishing of bluefin tuna. This decision was reached due to quotas for 2008 being reached two weeks early. Both countries questioned the commis-sion’s figures and asserted that their fishing industries had not reached even half their quotas. Environmental group Greenpeace said the incident was proof that more needed to be done to protect the species, calling for a fishing ban to allow stocks to recover.

More than 50,000 tons of blue-fin tuna are caught every year in the Mediterranean. To prevent stocks from collapsing, that figure should be limited to 15,000 tons in the short term, according to the International Commission for the Conservation of atlantic Tunas.

HoUse Committee oN NatUraL resoUrces sets its AgendA

On 21 November 2008, the U.S. House Committee on Natural Resources published its agenda for the 111th Congress. Items on the committee’s agenda include:

Planning for the Effects of Climate Change on Land and Water Resources Climate change is altering our natural landscape and affecting our water, land, and biological resources. For example, changing precipitation patterns related to climate change affect the ability of our water delivery infrastructure to capture and provide water in traditional ways. Further, both aquatic and ter-restrial species that rely on water for survival are adversely impacted by criti-cally dry times. The distribution of these species and their habitats is projected to shift in response to changes in ecologi-cal processes. At the same time, coastal and marine habitats and species will be impacted by sea level rise and increased ocean acidification. Understanding how climate change will affect the hydrologic cycle as well as our water, land, and biological resources and ensuring that federal agencies and states are prepar-ing to address how climate change affects their programs and management decisions is critical. The committee will continue its efforts to bring together sci-entists and the managers of our water, land, and biological resources to discuss the federal role in identifying the effects of climate change and to promote problem-solving strategies to sustain our natural resources and the ecosystems upon which they depend.

1872 Mining Law —Ending Corporate WelfareMultinational corporations are currently allowed to mine valuable hardrock minerals, such as gold and silver, from western federal lands without paying a royalty to the people of the United States and to allow corporations to purchase these lands at 1872 prices. During the 110th Congress, the com-mittee reported a comprehensive

Mining Law reform bill that took into account the public interest by imposing, for the first time, a production royalty and established a clear and enforceable set of environmental protections. The House passed this legislation on a 244-166 vote on 1 November 2007, and the committee will revisit this pressing issue during the 111th Congress.

Protecting and Restoring our OceansThe synergistic effects of human activity, including habitat destruction and over-fishing (domestically and internation-ally), as well as the spread of invasive species, climate change, and pollution have initiated changes of untold magni-tude. Science must inform the utilization of ocean goods and services so that the abundance healthy oceans provide can be enjoyed. Stewardship responsibili-ties will include realizing federal and regional ocean governance reforms, reviving our traditional international leadership role, implementing improve-ments in the management of fisheries and marine mammals, protecting special places in the marine environment as the inheritance of future generations, plan-ning for the effects of climate change and offshore energy development, and providing the funding necessary to set a meaningful pace of positive change. Recovering Endangered SpeciesThe Endangered Species Act (ESA) serves as the cornerstone of biodiver-sity conservation in the United States. The committee will work with the new Administration to explore innova-tive measures to recover endangered populations of fish, wildlife, and plants in an era of limited budgets.

aBstraCt: We review the ecology and conservation of three lesser-known chars (genus Salvelinus): Dolly Varden (S. malma), white-spotted char (S. leucomaenis), and bull trout (S. confluentus). Dolly Varden is distributed across the northern Pacific Rim and co-occurs with bull trout and white-spotted char at the southern extremes of its range. In contrast, bull trout and white-spotted char are naturally isolated, with the former restricted to North America and the latter distributed in northeastern Asia. Though the range of Dolly Varden overlaps with the two other chars, it is most closely related to Arctic char (S. alpinus), whereas bull trout and white-spotted char are sister taxa. Each species exhibits diverse life histories with respect to demographic characteristics, trophic ecology, and movement. This diversity appears to be tied to environmental variability (e.g., temperature, habitat connectivity), resource availability (e.g., food), and species interactions. Increasingly, these interactions involve nonnative species including nonnative salmonines and changes in food webs related to establishment of species such as Mysis shrimp in large lakes. As humans expand into the remote and pristine habitats that support these three chars, we encourage proactive consideration of the lessons learned where chars have already declined and internationally-based research and conservation.

evolución, ecología y conservación de las truchas “Dolly Varden,” “white-spotted” y tororesumeN: se revisa la ecología y conservación de tres truchas poco conocidas del género Salvelinus: Dolly Varden (S. malma), “white-spotted” (S. leucomaenis) y la trucha toro (S. confluentus). La primera se distribuye en el borde del Pacífico norte y co-ocurre con la trucha toro y la “white-spotted” en el extremo sur de su ámbito geográfico. En contraste, la trucha toro y la trucha “white-spotted” se encuentran naturalmente aisladas; la primera se restringe a Norte América y la segunda al noreste de Asia. A pesar de que el rango de Dolly Varden se sobrepone con el de las otras especies, está más relacionada con la trucha del Artico (S. alpinus) mientras que “white-spotted” y la trucha toro se consideran clados hermanos. Cada especie presenta diferente historia de vida con respecto a sus características demográficas, ecología trófica y movimiento. Esta diversidad parece estar determinada por la variación del ambiente (p. ej. temperatura y conectividad de hábitat) disponibilidad de recursos (i.e. alimento) e interacción con otras especies. Estas interacciones involucran cada vez más a especies no-nativas como algunos salmoninos y cambios en redes tróficas asociadas al establecimiento de ciertas especies como Mysis en los grandes lagos. En virtud de la expansión humana hacia hábitat más remotos y prístinos donde se distribuyen estas truchas, sugerimos que se tomen en cuenta de forma proactiva las lecciones tanto de aquellos casos en los que las poblaciones de truchas han declinado como del resultado de las investigaciones y esfuerzos de conservación a nivel internacional.

iNtrODuCtiON

Most research on salmonine fishes has focused on the genera Oncorhynchus (e.g., Pacific salmon, cutthroat and rainbow trout) and Salmo (e.g., Atlantic salmon and brown trout). Within chars, genus Salvelinus, work has focused mostly on Arctic char (S. alpi-nus), lake trout (S. namaycush), and brook trout (S. fontinalis). Though research on these species has provided a broad founda-tion for understanding the biology, ecology, and conservation biology of salmonines, even within this well-studied group gaps in understanding and uncertainties pose significant management and conservation problems.

here we focus on the biology and conservation of three lesser-known chars: Dolly Varden (S. malma), white-spotted char (S. leucomaenis), and bull trout (S. confluentus). We consider these species together because they share a similar Pacific Rim geog-raphy and evolutionary history, and provide an instructive com-parison of the conservation problems and uncertainties associated with management of native chars in North America and Asia. Our specific objectives are to: (1) provide a brief and selective overview of major aspects of the evolution and ecology of these three species, (2) compare and contrast conservation issues within and among the species, and (3) suggest priorities for future research and conservation efforts.

BiOGeOGraPhY aND eVOLutiONarY histOrY

Dolly Varden, white-spotted char, and bull trout are distrib-uted across the North Pacific rim (Figure 1). Dolly Varden is the most widespread of these species, occurring from Puget sound in Washington state, U.s.A., north to the Alaska Peninsula, Yukon, and Northwest Territories to far eastern Asia, including northern siberia and neighboring islands, south to hokkaido, the northern-most island of the Japanese archipelago (Armstrong and Morrow 1980; Reist et al. 1997; 2002). White-spotted char is distributed from honshu (the main island of Japan) north to the Navarin Cape, Russia (savvaitova 1980; Kawanabe 1989), on the Asian side of the North Pacific coast. Bull trout occupy coastal and inland drainages of western North America on both sides of the continental divide from Alaska and northern Canada to southern Oregon, but has been extirpated from the southernmost extent of its historical range in northern California, U.s.A. (Cavender 1978; haas and McPhail 1991; Reist et al. 2002). Both white-spotted char and bull trout overlap with Dolly Varden in portions of their respective ranges.

Recent evidence indicates that these three chars share a com-plicated evolutionary history. Allozyme, nuclear DNA, and mito-chondrial DNA (mtDNA) analyses all revealed sister groupings within Salvelinus that usually included one sister group compris-ing white-spotted char and bull trout, and one comprising Dolly Varden and Arctic char (Crane et al. 1994; Phillips et al. 1999; Crespi and Fulton 2003). A recent study based on mtDNA dem-onstrated, however, suggested that Dolly Varden and Arctic char do not constitute reciprocally monophyletic clades, which casts some uncertainty as to the distinct taxonomic status of these two species (Brunner et al. 2001). By contrast, a multilocus micro-satellite (nuclear) DNA examination of sympatric populations of Dolly Varden and Arctic char in western Alaskan lake sys-tems showed that sympatric forms were reproductively isolated from one another and acted as valid species (Taylor et al. 2008).

Consequently, historical introgression may be responsible for the relationship between Dolly Varden and Arctic char mtDNA observed by Taylor et al. (2008). historical and contemporary introgression has been reported between bull trout and Dolly Varden in populations that have a natural zone of overlap in North America (Taylor 2004), and between white-spotted char and Dolly Varden in Asia (Radchenko 2004; Yamamoto et al. 2006a). Evolutionary patterns within Dolly Varden, white-spot-ted char, and bull trout are unique for each species, both in terms of described subspecies and morphological variability.

Across the North Pacific rim, four subspecies of Dolly Varden are recognized: the northern Dolly Varden (S. malma malma Walbaum), the southern Asian Dolly Varden (S. m. kraschenin-nikovi Taranetz), the southern American Dolly Varden (S. m. lordi Günther), and the Miyabe char (S. m. miyabei Oshima; Figure 2). Chromosome and mtDNA data identified three phylogenetic groups, whose geographic distributions correspond to three Dolly Varden subspecies: S. m. malma, S. m. krascheninnikovi, and S. m. lordi (Phillips et al. 1999; Oleinik et al. 2005). Miyabe char inhabits only Lake shikaribetsu, hokkaido, Japan, which has been isolated historically due to volcanic activity. Miyabe char also has unique morphological characteristics in gill raker counts, pectoral fin length, the number of scales along the lateral line, and the muscle color compared to other conspecific populations (Maekawa 1984).

White-spotted char is presently separated into four subspecies based on zoogeographic patterns and morphological characteris-tics: S. leucomaenis leucomaenis (Pallas), S. l. japonicus (Oshima), S. l. pluvius (hilgendorf), and S. l. imbrius (Jordan & McGregor). Populations north of honshu Island, including hokkaido Island, Japan, and sakhalin Island and Kamchatka Peninsula, Russia, are classified as S. l. leucomaenis. They are characterized by large white spots (Figure 2; savvaitova et al. 2007). The other three subspe-cies are endemic to honshu Island, Japan, each with distinctive coloration. A recent phylogeographic study, however, has shown that the current subspecies designations of white-spotted char are not compatible with lineages identified with mtDNA markers (Yamamoto et al. 2004). Consequently, the taxonomy within S. leucomaenis remains in question.

At present, no subspecies of bull trout has been proposed, but the species was not formally described until relatively recently (Cavender 1978; haas and McPhail 1991). Within bull trout, multiple lines of evidence suggest at least two major evolutionary lineages in western North America: coastal and interior bull trout (e.g., Taylor et al. 1999; Taylor and Costello 2006), with further subdivision of these lineages proposed by other authors (Leary et al. 1993; spruell et al. 2003; Costello et al. 2003). As with Dolly Varden, these evolutionary groups within bull trout are associated with patterns of historical hydrographic connectivity (i.e., by the Coastal-Cascade Mountain Crest) across the geographic range of S. confluentus (haas and McPhail 1991). Patterns of phenotypic variability among populations have not been rigorously analyzed, as with other salmonines within the range of bull trout (e.g., O. mykiss; Keeley et al. 2005).

DiVersitY OF LiFe histOries

Around the Pacific Rim, Dolly Varden, white-spotted char, and bull trout each inhabit a broad geography of habitats that present a range of physiological conditions and patterns of resource avail-

Page 12: Fisheries · Fisheries • vol 33 no 11 • november 2008 • 531 Fisheries AmericAn Fisheries society • edITorIal / subscrIpTIoN / cIrculaTIoN offIces 5410 Grosvenor Lane, Suite

ability, as well as species interactions within distinct communities. This heterogeneity likely influenced resource polymorphisms and life history variation at a variety of scales, as has been observed in other species (e.g., smith and skúlason 1996). here we use the term “life history” in a broad sense to represent a broad range of phenotypic characters, including body morphology, age and growth, and feeding and movement behaviors. Within individual river systems, key factors influencing life histories include: local variability in temperature and flow patterns; the presence of lakes, reservoirs, and marine habitats in addition to widely varying riv-erine habitats encompassed by small channels in headwaters to expansive flood plains further downstream; and the strength of ecological connectivity among these different habitats (Ward and stanford 1995).

Age, growth, and reproduction

Dolly Varden and white-spotted char reportedly first mature between 1 and 7 years of age whereas bull trout are believed to mature later, generally between 5 and 7 years of age. Maximum life spans of these species may exceed 10–15 years (Rieman and McIntyre 1993; savvaitova 1980; Yamamoto et al. 1999; savvaitova et al. 2007). Rapid growth is often associated with movement into more productive environments, including the opportunity for piscivory. Dolly Varden, white-spotted char, and bull trout may reach maturity at sizes ranging from < 8 to > 80 cm (TL) depending on growth environments and differential selec-tive pressure on reproduction by males and females (e.g., Jonsson and Jonsson 1993; hendry et al. 2003). Migratory individuals that move from natal tributary streams into rivers, lakes, and the ocean occur in all three species; migratory individuals tend to mature at larger sizes (> 30 cm TL) compared to non-migratory or resident indivduals, which can mature at sizes down to 10 cm or less in small headwater streams (Koizumi et al. 2006a).

The timing and frequency of spawning can be highly variable. For example, in bull trout, spawning in inland habitats with colder winters and warmer summers may be initiated by late August, whereas in systems with lower seasonal variability (e.g., coastal environments; Brenkman et al. 2001) spawning may occur sev-eral weeks later. spawning in white-spotted char and bull trout is believed to be restricted entirely to stream environments, but wholly lake resident Dolly Varden have been reported from Alaska (Armstrong and Morrow 1980), Kamchatka peninsula (savvaitova 1973), and Kuril Onekotan (northern Kuril Islands; savvaitova et al. 2000). All species are iteroparous, but patterns of mortality during spawning have not been well quantified.

Trophic ecology

The striking trophic polymorphisms observed in Arctic char (e.g., Jonsson et al. 1988; Johnston 2002) have not been reported in white-spotted char or bull trout, but savvaitova and Kokhemenko (1971) reported discrete piscivorous and benthi-vorous morphs for Dolly Varden from large lakes in Kamchatka and the Kuril Islands (savvaitova et al. 2000). It is not clear whether these species have less capacity for the trophic special-ization observed in Arctic char or whether there has simply been too little work completed to recognize the full variability that may exist. At least one study suggested that some white-spotted char may develop dense gill rakers suited to foraging on plank-

ton (Takami and Kinoshita 1990). Evidence of trophic polymor-phisms for bull trout is lacking. Though trophic polymorphisms are not well documented for these species, considerable spatial and temporal variation in diet and plasticity in foraging behavior has been observed. Each species has achieved some notoriety for their opportunistic and often piscivorous habits (Behnke 1980; Takami and Aoyama 1997; Takami and Nagasawa 1996). Because of their proclivity to prey on salmon (Oncorhynchus spp.), all three chars were actively targeted for eradication in some early fishery management campaigns. For example, Colpitts (1997), elaborat-ing on trout conservation in southern Alberta between 1900 and 1930, described an attitude he termed the “hierarchy of species” where “handsomeness, gaminess, and edibility” ranked high, and fish imported from the East were generally considered superior to native predators such as the bull trout. The “better classes of fish” such as brook trout, cutthroat trout, and grayling (Thymallus arcti-cus) were coveted and reared in hatcheries to fill the void created by eradicating undesirable species. As Colpitts (1997) opined:

The bull trout’s failings—its image as a cowardly and lethargic sport fish, its flesh termed ‘insipid,’ and its character blighted by a reputation for cannibalism—targeted it among other species, for eradication by conservationists intent upon creating a perfect underwater world.

In spite of these perceptions chars have diverse diets, vary-ing from fish (including cannibalism) to invertebrates (e.g., Beauchamp and Van Tassell 2001). Moreover, these char display flexibility in their mode of foraging. For instance, Dolly Varden and bull trout have been observed to shift from drift-feeding on aquatic and terrestrially-derived invertebrates to picking benthic invertebrates from the benthos in response to diminished sup-ply of drifting prey or competition with other salmonines for this resource (Nakano et al. 1992; Fausch et al. 1997; Nakano et al. 1999a). Likewise, all three species are known to opportunistically shift to scavenging of fish eggs, especially those of Pacific salmon, but also those of conspecifics (Maekawa and hino 1987).

Movement

All three species commonly exhibit a great deal of variation in migratory behavior and related population characteristics. Migration typically is related to availability of food resources that are distant from natal habitat, and the relative benefits of migra-tion may vary between the sexes (e.g., Jonsson and Jonsson 1993; hendry et al. 2003; Koizumi et al. 2006a). Anadromy is common in white-spotted char and Dolly Varden but is more prevalent at higher latitudes (Yamamoto et al. 1999; savvaitova et al. 2007) where freshwater food webs are less productive and marine waters provide alternative food resources (Maekawa and Nakano 2002). Anadromy is also known in bull trout (Brenkman et al. 2007), though apparently is less common, perhaps because the species’ range is more inland in comparison to Dolly Varden and white-spotted char. some variability in migratory behavior in chars may also relate to variability in thermal requirements of different life stages. Quinn (2005) suggested that juveniles may emigrate from cold natal areas to find relatively warmer habitats where they are able to grow faster. In accordance with this hypothesis, char require very cold water (< 10 oC) for successful egg incubation (e.g., McPhail and Murray 1979), yet these cold habitats are not ideal for juvenile growth (selong et al. 2001). Likely, both food

availability and temperature interact to influence movement and migratory behavior of these chars (e.g., hughes and Grand 2000).

All three chars use a wide range of habitats, from small streams to large rivers, lakes, and marine habitats. however, few studies have been focused on their ecology during occupation of marine and large river habitats. Limited evidence suggests that within populations showing long-distance (> 20 km) migrations, larger (> 300 cm, TL) individuals tend to move quickly between natal habitats and migratory destinations, whereas behavior of smaller (< 30 cm) migratory individuals is more diverse and less predict-able (Muhlfield and Marotz 2005; Monnot et al. 2008). Thus, there may be important age or life-stage dependent patterns of migration, with variability in migratory behavior more complex than classic definitions based only on origins or destinations. In many cases, the actual “destination” of migration is not clear, as fish may use multiple habitats during migration (e.g., Brenkman and Corbett 2005), or change destinations among years (O’Brien 2001).

Another less-studied factor influencing migratory behavior is sex. small resident or so-called “precocious” males have been noted in Dolly Varden (Koizumi et al. 2006a; savvaitova 1960), white-spotted char (Morita and Morita 2002; savvaitova et al. 2007), and bull trout (Kitano et al. 1994; Baxter 2000). Even in populations considered to be largely migratory, mature, non-migratory males that adopt “sneaking” mating tactics probably occur, as this strategy is commonly observed in many other closely related salmonines (e.g., Esteve 2005). The occurrence of such individuals could be important, since they are unlikely to be con-sidered in typical counts of adults or spawning surveys.

In summary, movement is a defining feature of these chars, but our understanding of their movements and migrations have been largely limited to descriptive studies and a focus on localized pat-terns. Only a few examples of process-based movement studies exist and clearly more work is needed to explicitly frame move-ment and migration in a broader ecological-evolutionary context (Jonsson and Jonsson 1993; hendry et al. 2003).

Biotic interactions can be critically important in shaping the local distribution and abundance of chars. Char distribution may be affected by the availability of prey species, competition for these or other resources, regulation by predation or parasitism, or additional indirect interactions within their ecosystems (Fausch et al. 1994). Research on biotic interactions involving these chars has largely focused on their potential competition with other native and nonnative salmonines, whereas relatively little is known about interactions involving these char as predators or prey of native biota, or other roles they may play in ecosystems.

Interspecific competition with native salmonines

Though the geographic ranges of white-spotted char and bull trout overlap with Dolly Varden, they usually do not co-occur in the same local habitats (e.g., within a stream network). In regions where the species overlap, Dolly Varden usually occurs in colder upstream segments whereas either of the other two species occurs downstream, and there is typically a narrow zone of sympatry, although there are exceptions. For example, in hokkaido Island

this distribution pattern is observed for Dolly Varden and white-spotted char, and is correlated with changes in temperature across the region (e.g., climatic gradients) and within river networks (e.g., localized water temperatures; Fausch et al. 1994; Nakano et al. 1996). Presently, little is known about potential interac-tions that may occur between bull trout and Dolly Varden (but see hagen and Taylor 2001).

Interspecific competition with other native salmonines is considered important in causing exclusion of these chars or regulating coexistence with the other salmonines. For example, in coastal British Columbia lakes native coastal cutthroat trout (Oncorhynchus clarkii clarkii) exclude Dolly Varden from the productive near-shore littoral zone during summer where food resources are richest, causing them to shift to foraging in the open waters or deep benthic zone (henderson and Northcote 1985; hindar et al. 1988). In streams, salmonines compete for positions in mixed-species dominance hierarchies from which they can ambush drifting invertebrate prey (Nakano 1995). stream-living Dolly Varden shift, however, between drift and benthic foraging as availability of invertebrates varies (Fausch et al. 1997; Nakano et al. 1999a). This may result in partitioning food resources between Dolly Varden and white-spotted char in zones where they over-lap in hokkaido mountain streams, and promote species coexis-tence. At a larger scale, coexistence of these chars is regulated by condition-specific interactions and physiological responses to water temperature (Taniguchi and Nakano 2000). White-spotted char appear to dominate Dolly Varden behaviorally and grow relatively faster at warmer temperatures in downstream reaches, but Dolly Varden can persist where they are better adapted than white-spotted char to colder temperatures in upstream reaches. spatial patterns of segregation in other portions of the ranges of these two species may not parallel those observed in hokkaido streams, however (e.g, Kamchatka; J. stanford, personal observa-tion). Other than in their common role as piscivores, interac-tions between bull trout and other native fishes have received less research attention than Dolly Varden and white-spotted char, despite the potential for strong interactions with bull trout and co-occurring native species such as cutthroat trout (e.g., Nakano et al. 1992; Jakober et al. 2004).

Interactions with nonnative salmonines

In contrast to interactions with native salmonines that shape char distribution, the introduction and invasion of nonnative sal-monines has threatened to extirpate these three chars from many habitats throughout broad regions of their distribution via hybrid-ization, competition, and disruption of spawning. Nonnative chars such as brook trout and lake trout have been most commonly implicated in the declines of native char, although other spe-cies can be important. hybridization with nonnative brook trout has been reported for bull trout in northwestern North America (Leary et al. 1993; Kanda 1998; Kanda et al. 2002) and for white-spotted char in honshu and hokkaido Islands in Japan (suzuki and Kato 1966; Kitano 2004; Kitano, unpublished data), and may result in displacement of the native char through gamete wastage (Leary et al. 1993). Although introgression has been observed in bull trout (Kanda et al. 2002), limited viability in post-F1 crosses may limit development of hybrid swarms (e.g., Allendorf et al. 2001). The reported ecological impacts of nonnative brook trout on bull trout are highly variable and likely dependent on habi-

tat conditions and the spatial and temporal scales of observation (e.g., Nakano et al. 1998; Dunham and Rieman 1999; Rieman et al. 2006; McMahon et al. 2007). Impacts of nonnative lake trout on bull trout appear to be more consistently negative, but mecha-nisms of the interaction are similarly unclear (Donald and Alger 1993; Fredenberg 2002).

Rainbow trout (O. mykiss) and brown trout (Salmo trutta) are rapidly invading hokkaido Island (Takami and Aoyama 1999; Takami et al. 2002), and have been reported to exclude Dolly Varden and white-spotted char from foraging positions or habitats in hokkaido streams (Baxter et al. 2004; Morita et al. 2004; hasegawa et al. 2004; hasegawa and Maekawa 2006). In a field experiment, rainbow trout usurped terrestrial invertebrate prey on which Dolly Varden depend, and reduced their growth by 35% in 6 weeks compared to control reaches (Baxter et al. 2007). Rainbow trout introduced in North America could also compete with bull trout, but this has not been thoroughly inves-tigated (Boag 1987). In addition, spring spawning rainbow trout can reduce reproductive success of native fall-spawning char by excavating their spawning redds before the fry emerge (termed superimposition; Taniguchi et al. 2000). superimposition by fall-spawning kokanee salmon (O. nerka) on bull trout redds has also been documented, but at least in the latter case a study found that it was not harmful to bull trout due to the shallower depth at which the smaller nonnative kokanee (a form of landlocked sock-eye salmon commonly introduced in lakes) excavated substrates for spawning relative to larger bull trout (Weeber 2007).

Despite evidence for apparent displacement, there are cases where several of these salmonines appear to coexist with chars where their native ranges overlap. For example, Dolly Varden coexist with rainbow trout or steelhead in Alaska and Kamchatka rivers, probably by partitioning food resources via the foraging mode shift described above (see Dolloff and Reeves 1990; Fausch et al. 1997). since bull trout are naturally sympatric with either rainbow trout or cutthroat trout across most of their range, inter-actions with these species or with kokanee seem less likely to be negative and may even be beneficial in providing high quality food resources for bull trout. Indeed, many of the largest speci-mens of bull trout come from lakes with populations of introduced kokanee (Vidergar 2000; Beauchamp and Van Tassell 2001). Native lake trout and bull trout naturally coexist in certain drain-ages east of the continental divide in western North America, but when nonnative lake trout are established in lacustrine systems with native bull trout the latter are typically severely reduced or extirpated (Donald and Alger 1993). Examples of natural coexis-tence of lake trout with other chars are rare in other studied loca-tions, and coexistence may be facilitated by natural geomorphic barriers (hershey et al. 1999).

An important hypothesis is that the native char can resist invasion and persist in watersheds where intact habitat allows expression of the full range of life histories, including large, highly fecund, migratory individuals. When these migratory individuals are lost (e.g., through habitat loss or fragmentation, or overfish-ing), nonnative fishes may be better able to displace or replace the native char (Nelson et al. 2002). We view understanding the mechanisms that allow native chars to resist invasions by nonna-tive species, and the interactions of these mechanisms with habi-tat disruption, to be an important topic for future research.

Ecosystem roles

Relatively little is known about interactions involving these three char species as predators or prey in broader ecological com-munities, or other roles they may play in ecosystems. Bull trout are predators on other salmonines, especially Oncorhynchus spp. (O. nerka, O. clarkii, and O. mykiss) in lakes in the inland west-ern United states, where they become more piscivorous with increasing size (Ricker 1941; Beauchamp and Van Tassell 2001). During periods when Pacific salmon are concentrated, such as spawning or the out-migration of smolts, salmon eggs or juve-niles may become a temporarily important food for anadromous populations of Dolly Varden and white-spotted char (Armstrong and Morrow 1980; Kawanabe and Mizuno 1989). In turn, these chars may become prey for conspecifics and other piscivorous fishes and a host of semi-aquatic and terrestrial predators such as otters, bears, birds, or snakes.

Dolly Varden, white-spotted char, and bull trout likely have important effects on the structure of communities and the flow of energy and nutrients in the ecosystems they inhabit, though there have been few apparent investigations of these topics. Through their roles as predators on invertebrates and other fishes, these chars have the capacity to indirectly regulate organisms at lower trophic levels. For instance, two studies conducted in northern Japan (Nakano et al. 1999b; Baxter et al. 2004) showed that when terrestrial invertebrate prey were not available, Dolly Varden intensified their foraging on benthic invertebrates, which triggered an increase in the growth of algae but also reduced the emergence of adult aquatic insects and the abundance of spiders in the riparian forest. studies like these have not been conducted for bull trout or white-spotted char, but similar indirect effects on algae have been described for brook trout in a Canadian stream (Bechara et al. 1992). If predation by these chars can regulate prey fish populations in lakes, they could indirectly control phy-toplankton dynamics, as has been described for many other pis-civorous fishes, including lake trout and Arctic char (Carpenter and Kitchell 1993). Moreover, these chars, through their migra-tory life histories, can play roles yet to be described to link the food webs of multiple habitats, and they may also transport energy and nutrients as has been found for other migratory fishes (e.g., Gende et al. 2002). In sum, there is good evidence that chars play important ecosystem roles, and local extirpations or declines in these species may have much wider impacts than is commonly recognized.

ChaLLeNGes FOr CONserVatiON

Many of the conservation problems for Dolly Varden, white-spotted char, and bull trout have been elaborated using the tools of contemporary conservation biology. Population viability analy-sis has been applied to assess long-term persistence of bull trout and white-spotted char (Rieman and McIntyre 1993; Morita and Yokota 2002; Post et al. 2003; staples et al. 2005). In both species, sensitivity analyses have pointed to the importance of survival of older age classes to population persistence. Post et al. (2003) found that populations of migratory bull trout may be highly sus-ceptible to declines from increased mortality of larger, older fish due to angling. Bull trout (especially females) in such systems do not attain first maturity until at least 5 years of age. Morita and Yokota (2002) similarly found that survival of adults was impor-

tant for population persistence of white-spotted char in highly fragmented river systems. In their study system, however, white-spotted char matured at much smaller sizes and ages (e.g., most females were mature by age 2). Thus in both migratory bull trout and non-migratory white-spotted char, survival of older juveniles and adults appears to be a critical factor influencing population persistence.

Population viability analysis has provided important perspec-tives on the dynamics of individual populations of native char, but in most cases these local populations are embedded within a network of habitats and other populations. Within the context of a stream network, connectivity among populations (dispersal) and migrations among complementary habitats used for feeding, breeding, or refuge (schlosser 1991) are relevant. Aggregations of local salmonine populations likely exhibit complex dynamics and structuring that represent a composite of different metapopu-lation, landscape, and historical processes (Costello et al. 2003; Koizumi et al. 2006b; Whiteley et al. 2006). Because many of these processes can operate on large (> 10 km) spatial and long (> 10 year) temporal scales, they are very difficult to study with conven-tional ecological methods. single “snapshot” studies of large scale patterns of habitat or “patch” occupancy by bull trout (Dunham and Rieman 1999), white-spotted char (Morita and Yamamoto 2002), and Dolly Varden (Koizumi and Maekawa 2004) show that local population persistence in stream networks is strongly tied to patch size (stream or watershed size), connectivity, and quality (e.g., human influences, flow regime). The importance of habitat size and connectivity to persistence of chars documented by these studies is supported by several lines of evidence that examine temporal processes (e.g., dispersal, demographic variation, and environmental variability) driving these patterns. This includes evidence from models of population dynamics (e.g., Rieman and Allendorf 2001; Morita and Yokota 2002) and empirical applica-tions of molecular genetic markers. Results from the latter show that disruption of connectivity can lead to lower effective size of local populations by simultaneously reducing dispersal and local adult population sizes of native chars (Griswold 2002; Costello et al. 2003; Yamamoto et al. 2004; Whiteley et al. 2006; Koizumi et al. 2006b; Taylor and Costello 2006; Yamamoto et al. 2006b).

Although many ideas from contemporary conservation biol-ogy have played an important role in our understanding of native chars, several fundamental challenges remain to be addressed for the conservation of these species. As with most fishes, threats to Dolly Varden, white-spotted char, and bull trout are associated with past and present human influences on water resources that lead to habitat loss and degradation, loss of connectivity, invasion of nonnative species, and excessive harvest (legal, poaching, and incidental mortality; Post et al. 2003). As described above, many of these influences have driven populations to extinction in just a few decades (see Interactions with nonnative salmonines, above). Our experience parallels that of many biologists working with chars (e.g., Al-Chokhachy et al. 2008) in that it can be extremely difficult to quantify the influences of specific threats and interac-tions among them, for example, evaluating the tradeoff between isolating char populations with barriers to prevent invasions by nonnative salmonines versus restoring connectivity to allow native chars the ability to move throughout networks (Fausch et al. 2006).

Overall, the status of Dolly Varden, white-spotted char, and bull trout appears to show a general north to south trend in

the status of populations, with increasing imperilment near the southern margins of their ranges. For example, in the United states and Japan in particular, protected areas that support cur-rent strongholds of native chars are only small relicts of the range of habitats that were occupied in recent history. In the United states, many strongholds for bull trout are now located in higher elevation wilderness areas, whereas historically occupied areas were likely more expansive (Rieman et al. 1997). Distribution of bull trout has been consistently associated with unmanaged land-scapes with low human population influence as exemplified by the density of roads (e.g., Rieman et al. 1997; Baxter et al. 1999; Dunham and Rieman 1999; Ripley et al. 2005). Lower elevation habitats such as floodplains and riparian corridors of large rivers are critical to many salmonines, but they are also most likely to be highly altered by humans (Ward and stanford 1995; Beechie et al. 2003). In Japan, a large number of hatchery-reared white-spot-ted char have been stocked into lower elevation rivers and lakes. Consequently, populations of wild chars are often restricted to the upper reaches of rivers above natural waterfalls and human-constructed barriers that prevent the stocked fish from migrating upstream (Nakamura 2001). A focus on protecting only existing populations of native chars may therefore risk ignoring locations and/or habitats that are important for long-term viability.

Even though past changes are often clearly evident and impor-tant to Dolly Varden, white-spotted charr, and bull trout, possible future changes in populations and habitat are likely to pose even greater challenges. It appears likely that conditions will change substantially across landscapes in response to cycles of natural dis-turbance and succession processes (Reeves et al. 1995; Dunham et al. 2003). These natural processes will interact with human influ-ences, such as climate change (Nakano et al. 1996; Rieman et al. 2007; Rahel and Olden 2008), human land and water use (e.g., habitat conditions), fishing (harvest and indirect impacts), and impacts of nonnative species. Many case studies suggest that even large populations can become highly vulnerable if present condi-tions change. For example, bull trout were once very abundant and thought to be secure in Flathead Lake and the Flathead River system in northwest Montana, but populations quickly crashed in the early 1990s, due to major ecosystem changes and cascading food web interactions as a result of the introduction of a single nonnative invertebrate species, the opossum shrimp (Mysis rel-icta). This introduction disrupted trophic relationships between native (bull trout and westslope cutthroat trout) and nonnative fishes (lake trout, kokanee, and lake whitefish [Coregonus clupea-formis]) that had been relatively stable for nearly half a century prior to the Mysis introduction (spencer et al. 1991). We view analysis of these threats and planning for long-term persistence of chars (e.g., reserve design; Groves 2003) to be among the highest priority information needs for understanding long-term conserva-tion of the native chars considered here. On a more positive note, there are some examples of native char expanding rapidly once threats are mitigated, such as the rapid increase in populations of bull trout in the Metolius River basin of Oregon (Ratliff 1992) and in Lake Kananskis in Alberta, Canada (Johnston et al. 2007) following decreased harvest mortality.

and ecology of Dolly Varden, white-spotted char, and bull trout. Given the uncertain future for these species, we argue that these basic questions are directly relevant to applied conservation. For example, if we do not fully understand processes that contrib-ute to the development of evolutionary and ecological diversity within and among chars, how can we develop long-term plans to conserve this diversity? how can these chars coexist with other fishes in some locations, yet apparently not in other loca-tions? This question has direct relevance for managing invasive salmonines that may threaten native chars. What is the role of chars in aquatic ecosystems and how do food web interactions influence chars and ecosystems? In effect, the broad distribution of these species across both ecological and human geographies creates major challenges to addressing these critical questions about chars. More often our knowledge is based on a fragmented collection of isolated studies focused on narrowly framed issues of local interest. With this ad-hoc approach it can be very difficult to understand a species, and many of the questions we pose here are simply too broad to be adequately addressed in any particular locality. Accordingly, we encourage a stronger dialogue among biologists working across the ranges of these species and hope this synthesis represents an initial step in that direction.

Cooperative research is being con-ducted in many fields of research and development (e.g., education, physics, space science, materials research, com-puter science, clinical medicine) to lever-age the resources and expertise of multiple researchers from many institutions, pro-mote efficient use of labor, and enhance credibility (Maieschein 1993; Chompalov and shrum 1999; Crossley and holmes 2001). since the late 1990s, coopera-tive research in fisheries science has been expanding in the United states (U.s. Commission on Ocean Policy 2004; NRC 2004) and particularly in New England (hartley and Robertson 2006a), although recent federal funding constraints are threatening past gains. Cooperative research programs seek to directly involve the fishing industry and organizations in the design, planning, data gathering and analysis, and/or dissemination of findings from fisheries research. Further expan-sion is possible in spite of funding con-straints—the 2007 reauthorization of the primary U.s. federal fisheries management statute, the Magnuson-stevens Fishery Conservation and Management Act, added a section that establishes region-ally-based cooperative research and man-agement programs nationwide (see U.s. Public Law 109-479, Title II, §318).

Cooperative research Program Goals in New england:

Perceptions of active Commercial Fishermen

aBstraCt: Cooperative fisheries research will continue to expand throughout the United states with the 2007 reauthorization of the Magnuson-stevens Act, which called for the development of regionally-based cooperative research programs nationwide. We report on a survey of individuals actively engaged in commercial fishing in New England (N = 295) that asked how important and achievable cooperative research programmatic goals are and why. One goal, “the promotion of partnerships between fishermen and scientists,” was particularly important to fishermen because partnerships are believed to be in everyone’s interests, enhance the quality of the science, lead to better management decisions, improve the professional relationships between fishermen and scientists, and speak to a fishermen’s sense of professional duty. however, fewer respondents considered the partnership goal achievable because of a wide range of obstacles. Based upon the findings and published studies on the perceptions of scientists and mangers, we discuss recommendations for cooperative research managers.

Objetivos del Programa Cooperativo de investigación en Nueva inglaterra:

percepciones de los Pescadores comerciales activos

resumeN: A partir de la re-autorización de la declaratoria Magnuson-stevens en 2007, las sociedades cooperativas de producción pesquera han continuado expandiéndose a lo largo de los Estados Unidos de Norteamérica. La declaratoria es un llamado para el desarrollo de programas cooperativos de investigación a nivel regional. En este trabajo se reporta un sondeo realizado a todos aquellos individuos comprometidos activamente en la pesca comercial de Nueva Inglaterra (N = 295). En el sondeo se preguntó cuán importantes y asequibles son los objetivos de los programas cooperativos y por qué. El objetivo de “promover la sociedad entre pescadores y científicos” resultó ser de particular interés para los pescadores ya que tal asociación se asume de interés común, mejora la calidad de la ciencia, da como resultado mejores decisiones de manejo, enriquece las relaciones profesionales entre ambas partes y transmite el deber profesional al sentido común del pescador. sin embargo, debido a un amplio rango de obstáculos, pocos encuestados consideraron que este objetivo fuera asequible. sobre la base de estos resultados y otros estudios publicados acerca de la percepción de tienen científicos y manejadores, se discuten y dirigen recomendaciones a los directivos de investigaciones cooperativas.

In general, cooperative fisheries research is defined as fishermen-scientist partnerships that are classified along a spectrum from lower levels of engagement and cooperation with fishermen (e.g., log books, chartered vessels) to full “col-laborative” research, with fishermen and scientists working closely in all aspects of the research process (NRC 2004; Taylor singer 2006). Partnerships are central to cooperative research, although the degree of engagement of partners and integration of their knowledge and skills can vary. For the purpose of this article, we use the term “cooperative research” to mean all forms along the continuum from cooperative to collaborative.

several models of cooperative research can be found in New England, including industry sectors setting aside a portion of their profits for research, competitively-awarded federal resources dedicated to cooperative fisheries research (both uni-versity and National Marine Fisheries service [NMFs] administered programs), and non-profit community development loans with cooperative research contract conditions. Nationwide, certain areas of the United states are more active in cooperative fisheries research than oth-ers. Early ground-breaking cooperative research, particularly in the late 1980s on turtle excluder devices (TEDs) in shrimp trawling gear, emerged out of the south-eastern United states through sea Grant and a NMFs science center (NRC 2004; Graham 2006). however, since 2000, better funded and more institutional-ized cooperative research programs have been established in the Northeast, Pacific Northwest, and Alaska (Karp et al. 2001; harms and sylvia 2000; Pautzke 2006). These regions have become the leaders in advancing cooperative research program designs (Read and hartley 2006).

One example of a university-based, regional program is the Northeast Consortium, created in 1999. Four research institutions (Universities of New hampshire and Maine, Massachusetts Institute of Technology, and Woods hole Oceanographic Institution) work with a multi-stakeholder advisory panel to administer cooperative research outreach, education, competitive grant-making, and science and data management (www.north-eastconsortium.org; hartley and Robertson 2006a). The Northeast Consortium is a $5 million annual program and as of January 2008 had underwritten 171 collaborative

research projects (nearly 90 projects were complete), involving over 355 fishing ves-sels captains/owners, 33 fishing industry organizations or businesses, and over 221 scientists from 55 research institutions or agencies on a wide array of fisheries, gear, ocean process, and socioeconomic topics within the Gulf of Maine and Georges Bank. The Northeast Consortium’s goals are to:

1. Develop partnerships between com-mercial fishermen and scientists, edu-cators, and coastal managers;

2. Enable commercial fishermen and com-mercial fishing vessels to participate in cooperative research and develop selec-tive gear technologies;

3. help bring fishermen’s information, experience, and expertise into the sci-entific framework needed for fisheries management; and

4. Equip and utilize commercial fishing vessels as research and monitoring platforms.

These four goals were established through discussions of a 30-person multi-stake-holder Advisory Committee (hartley and Robertson 2006a). Further, the Northeast Consortium has been recognized nation-ally and internationally as a model for effective cooperative research program-ming (Gallant 2005).

This article briefly reviews the current literature on the human, social, and insti-tutional dimensions of cooperative fisher-ies research, followed by the presentation of a particular study in New England. We report on a survey of individuals actively engaged in commercial fishing in New England that examined the perceptions of this important set of industry leaders regarding how important and achievable the cooperative research programmatic goals of the Northeast Consortium are and why. Further, while research on fish-eries scientists and managers was beyond the scope and funding of this study, past research and other data are presented from multiple sources to discuss fisheries scien-tists and managers’ attitudes toward the cooperative research goals. We conclude with a discussion of these findings relative to cooperative natural resource manage-ment and science and some recommen-dations for cooperative fisheries research managers.

humaN, sOCiaL aND iNstitutiONaL DimeNsiONs OF COOPeratiVe researCh

To date, there has been limited but growing empirical research on the human, social, and/or institutional dimensions of cooperative research. however, a body of literature provides testimonies and case stories about cooperative research and perceptions about its human and social dimensions. For example, during the 1990s a fisheries resource crisis in Nova scotia led to the creation of the Fishermen and scientists Research society (see www.fsrs.ns.ca/), which emerged from a context of distrust among fishermen and scientists and limited use of fishermen’s knowledge or human resource capability in fisher-ies science (King 1999). Program lead-ers identified the building of trust among parties and the enhanced credibility of the scientific findings as outcomes of cooperative research, and particularly the frequent, joint activities leading to a “common language and…better under-standing of each other” (King 1999:10). While maintaining frequent, direct com-munication, including feedback to fisher-men about research results, the program still experienced a drop in motivation and participation among industry over time.

science managers in NMFs have reported that they believe fishermen are interested in focused cooperative research on immediate concerns in fisheries resource management, and that coopera-tive research builds mutual understand-ing and respect between scientists and fishermen (sissenwine 2001). Michael sissenwine stated in Congressional testi-mony, “Our overwhelming experience has been that people working together learn to understand each other’s perspectives, regardless of personal backgrounds. Owing to this, I believe those who participate in cooperative research will be more respon-sible in fisheries and fisheries management for the rest of their careers, regardless of their roles” (2001:5).

Fishing gear research aimed at reduc-ing bycatch of species of concern has expanded tremendously over the last few decades and it is a particularly active area for fishermen-scientist partnerships. Early bycatch research in Australia in the 1990s demonstrated that cooperative research strategies led to substantial bycatch reduc-tions in prawn trawl fisheries. Reductions were achieved in large part because the

Page 25: Fisheries · Fisheries • vol 33 no 11 • november 2008 • 531 Fisheries AmericAn Fisheries society • edITorIal / subscrIpTIoN / cIrculaTIoN offIces 5410 Grosvenor Lane, Suite

cooperative research placed industry in a publicly visible leadership role in solving the problem, and integrated fishermen’s knowledge into the design of feasible gear technology designs (Kennelly and Broadhurst 1996). As a result, the research findings were more acceptable to the indus-try and adopted voluntarily (Kennelly and Broadhurst 1996).

In one of the early empirical reports on the human dimensions of cooperative research, Conway and Pomeroy (2006) surveyed 15 scientists, fishermen, and sea Grant extension agents involved in a collaborative fisheries habitat research project. They identified four interests and motivations among participants: interest in the research topic, opportunity to learn from others, facilitation of the connection and communication between fishermen and scientists, and the importance of bring-ing fishermen’s knowledge into scientific research. While there were specific chal-lenges posed by the research project (time, funding, weather and seasonal conditions, and the communication challenges arising from limited face-to-face time), specific benefits were identified as well. The ben-efits included mutual learning, improve-ments in data collection methods, and the generation of high interest in continuing to collaborate on research. Further, Conway and Pomeroy reported the improve-ment of professional relationships among three partners, although one respondent reported a worsened relationship with a scientist. Bernstein and Iudicello (2000) also found complex social dynamics among partners in a review of seven cases in the U.s. fisheries. specifically, they reported that the effective motivations to participate in cooperative research depend upon the culture of the individual fishery and the personal relationships that existed among participants.

The challenges of cooperative research have been well reported (NRC 2004; Conway and Pomeroy 2006; Read and hartley 2006; Jones et al. 2007) and include, time, resources, staff capacity, information and data management, over-coming mistrust, and inadequate com-munication and coordination. The 2004 National Research Council (NRC) assess-ment of cooperative research in NMFs included a discussion of the social con-text of cooperative research. The NRC reported that the fishing industry had little confidence in science and used the political process to oppose regulations,

but improvements arose through coop-erative research. specifically, NRC heard examples of cooperative research leading to greater confidence in data, analysis of the data, and the resulting management recommendations.

hartley and Robertson (2006a) linked the emergence of cooperative fisheries research in New England to the mid-to-late 1990s climate of socioeconomic hard-ship in fishing communities, depressed fish stocks, and intense distrust and debate between scientists and fishermen over fish-eries science. In New England, a general lack of trust and respect remains between fishermen and scientists, although fisher-men participating in cooperative research reported forming better partnerships with more trust in scientists and creating more credible science than they had expected (hartley and Robertson 2006b). Both fishermen and scientists participating in cooperative research in New England report greater mutual understanding, trust, and likelihood of long-lasting partner-ships; nonetheless, both remain skeptical that cooperative research findings will impact fisheries management (hartley and Robertson 2006b).

In sum, past research has clearly dem-onstrated that the social context underly-ing the professional relationships between scientists and fishermen in cooperative research is multifaceted and presents sub-stantial challenges to effective coopera-tive research. It is not yet clear if and how these factors differ between “cooperative” and “collaborative” forms of cooperative research. Nonetheless, it could be hypoth-esized that more collaborative forms require even greater attention to the fac-tors underlying the partnerships. The ben-efits discussed in the literature appear to directly counter many obstacles—in other words, while distrust, lack of credibility, and misperception inhibit cooperative research, at the same time, cooperative research seems to improve levels of trust, credibility of science, and degree of mutual understanding and communication. Thus, understanding the human dimension of scientist-fishermen partnerships will very likely improve the design and implemen-tation of cooperative research programs.

The research reported here focused on actively engaged commercial fish-ermen (i.e., currently fishing and not latent permit holders), a very important stakeholder group in New England’s fish-ing industry. More specifically, the study

examined their beliefs in the importance and achievability of particular cooperative research goals, especially the perceived opportunities and challenges of promot-ing fishermen-scientist partnerships. We asked individuals engaged in commercial fishing how important and achievable specific cooperative research objectives were and why. A follow-up open-ended “why” question provided qualitative data insightful in assessing the perceived barri-ers to achieving these cooperative research objectives in New England, which in turn has informed and guided Northeast Consortium programming.

The survey was designed and adminis-tered using standard data collection pro-cedures and quality controls detailed in Dillman’s Tailored Design Method (1999). Addresses were obtained via a mailing list provided by the New England Fishery Management Council in 2001, which had originally come from the NMFs fish-ing permit holders list. To ensure that the researchers and the research instru-ment did not bias the survey response, drafts were reviewed and pre-tested with an industry and scientist advisory group. The survey was administered to individu-als who were actively engaged in feder-ally-managed commercial fishing in New England in 2002–2003.

The first questionnaire mailing was sent to 1,204 individuals in fall 2002 and, after removing undeliverable addresses and returned surveys, there were four follow-up mailings of two different survey lengths until summer 2003. Respondent occupations for each returned survey were examined and questionnaires from non-commercial fishermen were eliminated from this analysis, leaving 295 respondents out of 420 commercial fishermen (N = 295, 70% response rate). The mean age for respondents was 52 years old with 27 years of fishing experience. Most owned or oper-ated more than one vessel (1.45 mean) and employed a small crew (5.36 mean and 3 median). Fifty-five percent (55%) of respondents earned over three-quarters of their income from commercial fishing and the average respondent participated in nearly four (3.98) different fisheries (i.e., target species, gear types, inshore/off-shore). Overall, the respondents were quite engaged in fisheries management activi-ties: 72% attended fisheries management

council meetings, 69% contributed money to fishing causes, 67% called government officials, and 63% had commented on a fishery management plan. The commercial fishing industry in the Gulf of Maine and Georges Bank is a relatively small, self-selected population with only a few thou-sand participants and it is getting smaller through attrition and increasingly restric-tive regulations (hall Arber et al. 2001). It is generally difficult to obtain large sample sizes from this population.

Follow-up contacts were made with questionnaire non-respondents in order to better understand the response bias in this study. There were no significant differences across size or format of questionnaires, i.e., long versus shorter versions. There were significant differences across the states, Maine, New hampshire, Massachusetts, Rhode Island, and Connecticut (chi-square 13.73 – sig., 0.008). specifically, Massachusetts fishermen were the most likely to be non-respondents. There were no significant response rate differences across all the fishing practices or behaviors (i.e., level of engagement, fishing sector, and attitudes towards and support for coop-erative research) and demographic vari-ables. Nonetheless, while we concluded that there is a potential for response bias between states and the sample list is biased toward more actively engaged commercial fishermen in northern New England, the focus of this article was not impacted by the non-response bias because we were more interested in the views of the engaged sub-sample than the broader population of commercial fishermen. The response bias and the study’s focus on engaged fisheries leaders make it inappropriate to general-ize about the broader commercial fish-ing industry in New England or beyond. Nonetheless, the 295 respondents reflects

one of the largest sample sizes of commer-cial fishermen in the published literature.

Further, the survey included open-ended questions asking why the fisher-man answered the scaled (not, somewhat, very) importance and achievability ques-tions for each Northeast Consortium goal the way they did. We present here an analysis of the comments made by 164 respondents regarding the importance and achievability of one of the Northeast Consortium’s objectives, i.e., promoting partnerships. This reflects all answers from the 295 total respondents. No differences were observed in responses to quantita-tive measures of partnership importance and achievability among respondents of different fishing practices or behaviors or other demographic variables. We elected to present qualitative data on this single goal because partnerships are central to all forms of cooperative research, and the partnership goal exhibited one of the larg-est discrepancies between importance and achievability ratings. The qualitative data underwent standard content analysis and quality control protocols that identified themes and patterns in segments of text comments (Lofland and Lofland 1995 Miles and huberman 1994). Two investi-gators independently coded samples of text responses for attributes of importance and achievability and then consulted on final coding protocols, before one investigator completed the coding. subsequent cod-ing and recoding was confirmed with the second investigator after approximately one-quarter, half, and three-quarters of the data coded. All 164 comments were coded and clustered into overarching themes.

resuLts

Overall, active commercial fishermen respondents considered the cooperative research objectives to be very important, although not very achievable (see Table 1). The goal of integrating fishermen’s knowledge into the scientific framework was considered the most important among the four goals. The most exact, yet narrow goal, i.e., equipping and utilizing com-mercial fishing vessels in research, was considered the most achievable among the goals, although it was also considered less important than the other objectives. Meanwhile, the broader partnership goal was considered less achievable than other goals. Nonetheless, overall the respon-dents remained somewhat optimistic, with between 88% and 93.5% believing that goals were either somewhat or very achievable.

A mix of chi-square and one-way anal-ysis of variance was used to examine the relationship between demographic and attitude and opinion variables associated with the sample of commercial fishermen included in this study. A few significant differences were observed, although differ-ent demographic groups were more alike than different. For example, fishermen were significantly more likely to believe that the goal of integrating fishermen’s information, experience, and expertise into the scientific framework was impor-tant if they had contributed money to fishing causes (p = .002), served on a plan development team (p = .005), contacted a government official (p = .007), or spoken at a fisheries management council meeting (p = .07). Fishermen who participated on a plan development team were also more likely to believe that the developing part-nerships goal was important (p = .005).

Other demographic characteristics (e.g., gear type, home port, etc.) did not show statistical significance.

A content analysis of the qualita-tive data regarding why active fishermen respondents considered particular goals important revealed several motives and opportunities for cooperative research in New England, while the responses to why fishermen considered particular goals less achievable identified potential barriers (see Table 2 for a summary of themes). The themes do not reflect completely independent ideas, as there is overlap and a continuum of social factors at play. Rather, the themes identify underlying social phenomenon that influence beliefs, attitudes, and opinions about the partner-ship objective.

Many fishermen perceived that it is in everyone’s interest to participate as a partner in cooperative research. The majority of qualitative responses to the “why partnership is important” question related to the perceived common interest in a healthy stock and its relationship to a healthy, viable fishing industry. sample responses coded as this common interest in a healthy fish stock theme included, “Everyone wants to save the resource,” and, “In order to survive, we'll all need to work together.” Further, the second most often mentioned opinion was that partnerships are important because they enhanced the quality of the science and the resulting fish-eries management decision. For example, fishermen wrote, “Better science = more effective management,” and “Fisheries sci-ence and data [are] not always accurate.” Active commercial fishermen in New England also mentioned that partnerships are important because they may improve the professional trust and mutual under-standing among fishermen and scientists, e.g., “to build trust,” and “we can learn

from research and they can learn from us.” Further, fishermen expressed an expecta-tion or sense of professional duty that they should be partnering and participating in cooperative research; fishermen noted, “Fishermen need to participate in all lev-els of the recovery,” and “[Cooperative research partnerships] will become neces-sary in time.”

In explaining why achieving the part-nership goal may be more challenging, fish-ermen identified many obstacles, including the fishermen’s mistrust and suspicion of scientists and managers (see Table 2). For example, fishermen noted that “trust has been broken too many times,” referring to the perception that fishermen have been harmed by partnerships in the past. Another wrote, “Fishermen distrust sci-entists.” The level of mistrust may extend to active suspicion among some, as one fishermen wrote, “NMFs wants us out of business,” and another added, “Fisheries managers have preconceived answers, which they hire researchers to prove; if the information they gather is contrary, they discard it.”

While active commercial fishermen from New England reported that a com-mon interest between fishermen and sci-entists was a reason that partnerships were important, fishermen also reported that a lack of common interest with scientists inhibited partnerships and made partner-ships less achievable. Fishermen wrote, for example, “Never the two shall meet!” and “Lines have been drawn, walls have been built.” Another fisherman summed up ele-ments of mistrust, suspicion of the man-agers' motives, and the lack of common ground by writing, “We give information on our business; they make a living with this and we get restricted!” Active com-mercial fishermen in New England feared

that cooperation would not be in their best interests.

Negative stereotypes about scientists were observed in the qualitative data, e.g., perceptions of arrogance and disre-spect among scientists toward fishermen. Fishermen wrote, “No one respects fish-ermen,” and, “scientists view fishermen as the enemy.” Other fishermen noted, “NMFs scientists think they are better than fishermen. They look down on us.” still a fourth fisherman added, “scientists think they have all the answers.” Finally, fisher-men acknowledged poor communication and little mutual understanding between fishermen and scientists. One fisherman stated, “Academia and managers do not listen!” Another added, “No one listens to fishermen,” and a third said, “Researchers never listen to fishermen.” At the same time, one fisherman acknowledged “fisher-men lack fisheries education.”

The twenty-three quotes reported above were from different respondents and represents a small fraction (14%) of the total 164 qualitative responses coded and clustered into the motivation and obstacle themes summarized in Table 2.

DisCussiON

Based upon the quantitative analysis alone, there was clearly substantial sup-port for cooperative research objectives among active New England commercial fishermen, with > 97% rating the goals as very important and > 88% rating them as somewhat or very achievable. While a strong belief in the importance and the somewhat less strongly held belief in the achievability of goals was universally held across the active commercial fishing indus-try respondents in New England, fishermen who participated on plan development teams were among the most adamant in

their belief in the importance of partner-ships and integrating knowledge. This group, along with participants on other management committees (e.g., advisory panels, technical panels, council research steering committees, etc.), likely may be strong advocates for cooperative research. Further, they are better positioned to influ-ence policy and management than the other respondents who stood out among the sample (i.e., fishermen who contrib-uted money to fishing causes, contacted government officials, and/or spoke at a fisheries management council meeting). In fact, the level of management engagement was a better predictor of strong support for integrating fishermen and scientific knowl-edge and importance of partnerships than gear type, sector, fishery, home state, or other fishing industry demographic. These management-active fishermen may be benefiting more directly from additional cooperative research-derived information and could be in a position to advance the science-to-management impacts of coop-erative research. Consequently, tailoring programmatic communication and out-reach activities to this important sub-set of commercial fishermen could enhance impact and program effectiveness.

Fishermen mentioned that a sense of professional duty contributed to why it is important to form cooperative research partnerships. In a nationwide review, Read and hartley (2006) reported that cooperative research promotes a sense of stewardship among the fishing indus-try. This suggests that there may be an emerging professional norm among com-mercial fishermen—an expectation that to be a fisherman, they should participate in research and monitor the health of the ecosystem and the fish stocks. Research on common property resources has suggested that it is critical to have the resource users actively involved in monitoring the health of the resource in order to achieve sustain-ability (Ostrom 1990). Future research could examine whether the sense of pro-fessional duty reflects the beginning of the integration of research into a stewardship ethic among fishermen. If this human dimension of cooperative research is real, the institutional integration of coopera-tive research into management regimes, including co-management, ecosystem-based management, etc., could be critical to achieve sustainability of the resource.

A belief in a common interest among fishermen, scientists, and managers was a

frequently mentioned reason among active New England fishermen for the importance of forming cooperative fisheries research partnerships; however, it also proved to be an obstacle. On one hand, there was a per-ception that “everyone wants to save the resource,” as one fishermen stated; while on the other, there was fear that another fishermen articulated as “whenever fisher-men help with data, it slaps them in the face.” Fishermen thought there ought to be a common interest among fishermen and scientists (particularly an interest in healthy, viable ecosystems, fish stocks and fishing communities), although in practice they did not often see common ground (see Dobbs 2000; hartley and Robertson 2006a). This scale difference between gen-eral, broad common interests in a resource, and more narrow interests in specific fish-eries or fishermen is substantial and the divide between fishermen and scientist on this issue remains wide. The phenom-enon of the same individual holding dif-ferent attitudes toward the same interest when applied at different scales (public good versus individual interests) has been seen in other resource and environmen-tal management contexts, e.g., water resource management (Bruvold 1988), land use planning (schively 2007), and waste management (Rabe 1994; sjöberg and Drottz-sjöberg 2001). Nonetheless, interest in participating in cooperative research in New England continues to grow (Northeast Consortium 2007), in spite of the perceived risk among fisher-men. Cooperative research managers can-not deny that the fishermen’s perceived risk from partnerships is real.

Last, given that mistrust, as an obstacle to achieving partnerships goals, is so strong among fishermen that some suspect that scientists and managers are out to harm them, NMFs and cooperative research program managers should not expect that simply denying the perceived vengeful interest will eliminate this concern among fishermen. Trust is earned and not granted (Lewicki and Bunker 1995); thus, over-coming this suspicion will take time and a consistent pattern of constructive scien-tist-fishermen partnerships. Much of the previous literature on the human dimen-sion of cooperative research identifies the importance of trust; it can be needed to permit cooperation and at the same time, trust can grow with cooperation. however, trust is a large, complex, social construct that needs further research in the context

of cooperative research. Further, hartley and Read (2006) reported that inconsis-tent funding can undermine the ability of cooperative research programs to dem-onstrate the pattern of commitment nec-essary to build trust. Consequently, the funding shortfall emerging in cooperative research today could seriously set back the trust built since 2000 in New England.

sCieNtists aND maNaGers

The findings reported here provide insights into the beliefs of a critical stake-holder in cooperative research and fish-eries managers, i.e., the actively engaged commercial fishermen, particularly in New England. At the same time, the attitudes of participating scientists and managers, particularly toward the impor-tance and achievability of cooperative research goals, is an important question too, although beyond the scope of this research project and funding. Do sci-entists and managers share the views of fishermen or are their attitudes, opinions, and perceptions different?

Past research has provided some indication of the substantial differences between fishermen and scientists. For example, the Kennelly and Broadhurst (1996) case examples discussed above include insights on stakeholder differ-ences in the diffusion process of cooper-atively-derived gear technologies. While scientists and engineers were convinced of the effectiveness of the gear designs by the data analysis and graphical interpre-tations, fishermen who did not directly participate were more convinced by pho-tographs, videos, and meetings with the scientists and fishermen who did partici-pate in the research. These participating fishermen helped other fishermen make and use the gear modifications and the grapevine among fishermen lead to adop-tion of the gear in other ports through-out eastern Australia. so scientists and fishermen may find very different types of information and data convincing and may disseminate their knowledge differently.

For their part, scientists are gener-ally unfamiliar with collaborative pro-cesses and can be reluctant to participate (hinkey et al. 2005; NAs 1995). Conway and Pomeroy (2006) reported that scien-tists, fishermen, and university extension staff perceived their involvement on the same cooperative research project dif-ferently. scientists viewed the project as

Page 29: Fisheries · Fisheries • vol 33 no 11 • november 2008 • 531 Fisheries AmericAn Fisheries society • edITorIal / subscrIpTIoN / cIrculaTIoN offIces 5410 Grosvenor Lane, Suite

Fisheries • vol 33 no 11 • november 2008 • www.fisheries.org 557

more cooperative (joint activities and tasks) versus collaborative (more intel-lectually integrated) than fishermen and extension partners, as defined by Conway and Pomeroy. Extension staff considered the same project as more collaborative than cooperative, when compared to participating scientists and fishermen. hinkey et al. (2005) reported that sci-entists struggle to understand and accept a collaborative process. Thus, scientists and fishermen likely experience the same event differently.

Nonetheless, hartley and Robertson (2006b) have reported some similar outcomes among 60 fishermen and 37 scientists from their act of participation in cooperative research. Fishermen and scientists both claim that they are more likely to enter long-lasting partnerships as a result of cooperative research; a similar finding was reported by Conway and Pomeroy. Fishermen and scientists (to a lesser extent) are more engaged in fisheries management after participating in cooperative research, although they both remain skeptical about coopera-tive research’s impact on management. Finally, fishermen and scientists both report achieving greater mutual under-standing and trust than expected from participating in cooperative research.

Further, hartley and Robertson (in press) also examined whether knowledge integration was important and achiev-able and whether and how fishermen and scientists learned about the scientific pro-cess or fishing practices, respectively from participating in cooperative research. They found that active commercial fishermen believed that scientists did not respect or value their information. Nonetheless, scientists who participated in cooperative research reported learning from fishermen and did not express the level of distrust and disrespect for fisher-men or fishermen’s knowledge that the active commercial fishermen perceived. While this could be due in part to those electing to participate being pre-disposed to collaboration and learning about oth-er’s perspectives, knowledge integration resulting from the act of participating in cooperative research also appeared to be occurring in participating fishermen and scientists.

While this past research and the forthcoming publication of data from participating scientists in Northeast Consortium-funded cooperative research

provides some insights into the percep-tions of scientists, they do not answer the question about scientist’s perceived importance and achievability of partner-ships discussed in this article. Further, data on manager’s perceptions are lacking in the literature. These remain important future research questions.

CONCLusiONs

New England cooperative research program managers need to work to over-come mistrust and suspicion, a lack of mutual understanding about each oth-er’s interests, misperceptions and nega-tive attitudes, and poor communication. Cooperative research provides a venue for communication, addressing these underlying human dimensions of coop-erative research and management.

These data also suggest very high expectations among active New England fishermen for what should be achieved from cooperative research. since high expectations may decline significantly if results are not clearly demonstrated in a reasonable amount of time, it could be critical for cooperative research program managers to understand what the moti-vations, opportunities, and obstacles are to achieving program goals. New England fishermen who are actively fishing today seem to think cooperative research is important, but they are less convinced it will make a difference. This fact, in part, contributed to a set of Northeast Consortium adaptations that expanded science-to-management activities—specifically, Northeast Consortium staff administer scientific peer reviews of each cooperative research project’s final reports and data. Project final reports and accom-panying peer-review reports are then pre-sented by Northeast Consortium staff, sometimes in conjunction with the proj-ect’s principal investigators, to the New England Fisheries Management Council through its Research steering Committee. Further, the Northeast Consortium spon-sors a web page with a map-based inter-face that serves all peer-reviewed data from Northeast Consortium-funded proj-ects. Additional research on the science-to-management process would provide further insights into helpful program-matic adaptations.

It has already been noted that coop-erative research provides important new communication venues for fishermen and

scientists; however, additional commu-nication opportunities should be sought. Cooperative research managers should design and host safe, secure places for communication between fishermen, sci-entists, and managers (e.g., regular project participant meetings, symposia and panels at scientific conferences and professional trade shows, cooperative research work-shops, and community celebrations).

Finally, effective cooperative research programs need to be tailored to the regional context (Read and hartley 2006). At the same time, lessons learned and experiences from active regions (e.g., New England, Alaska and the Pacific Northwest), such as those reported here, should also be shared with other regional initiatives so that programs can be suc-cessful and meet high expectations as quickly as possible. A network of regional initiatives and dialogue within profes-sional associations, such as the American Fisheries society, could more rapidly share, advance, and coordinate the suc-cesses and best practices of cooperative research. The U.s. Commission on Ocean Policy (2004) recommended a network of regional initiatives; however, given the need to balance local- and region-specific effectiveness with communication and information sharing nationally, Glass (2006) suggested a network of regionally-tailored, university-based initiatives. The re-authorized Magnuson-stevens Act states that the federal government “shall establish a cooperative research and management program… implemented on a regional basis and shall be developed and conducted through partnerships among federal, state, and tribal manag-ers and scientists (including interstate fishery commissions), fishing industry participants (including use of commercial charter or recreational vessels for gather-ing data) and educational institutions”—see U.s. Public Law 109-479, Title II, §318(a). however, for the regionally-tailored, national network to be most effective, it should be an active learn-ing organizational network that shares information and lessons learned, and systematically monitors the effectiveness of cooperative research programming. Understanding the perceptions of active commercial fishermen and their attitudes toward cooperative research, along with other human dimensions of cooperative research, will be critical to achieve these national goals.

LETTERS: To THE EDIToR

Hansen and Jones (2008) perpetuate the naive perception that “failures” in fisheries management are all or in sub-stantial part due to uncertainty in results from traditional fishery stock assessments, and that increasing the investments in data gathering and stock assessments may not improve the management of commercial fisheries in the future. In fact, the overwhelming evidence (e.g., Mace 2004; Hilborn 2004, 2006) indicates that, where overfishing and resource deple-tion have occurred, it is overcapitaliza-tion and intransigence to implementing controversial but necessary short-term conservation measures—often in the face of clear scientific evidence from fisheries stock assessments—that has led to such declines. We submit that the clearer the scientific evidence is for such measures, the more likely it is that they will be adopted.

The steady decline in the proportion of federally-managed U.S. fisheries subject to overfishing (17% as of the second quarter of 2008; NOAA 2008a) is due to the incorporation of traditional stock sta-tus research into the fishery management council process. Over the next 18 months, regional fishery management councils, acting on traditional stock assessment information, will propose measures to eliminate overfishing in this country. Draft guidelines issued for the fishery management process further emphasize the importance of incorporating uncer-tainty in the establishment of fishery targets that will prevent thresholds from being exceeded (NOAA 2008b). A more problematic issue than the uncertainty of existing assessments is the fact that only 56% of the 230 most important fishery stocks in the United States currently have adequate population assessments. Doing “cheap and dirty” assessments under-mines the credibility of science support-ing management and promotes costly litigation. Such assessments will be prone

to undetected biases, leading to man-agement decisions that jeopardize the long-term sustainability of fish stocks and ecosystem integrity.

The dashed line in Figure 1 of the Hansen-Jones article depicts their questionable assumptions that funding for the totality of the fishery manage-ment process is fungible but fixed, and implies that increasing the risk of bad decision making does not have financial consequences. It seems more likely that higher levels of funding for information gathering will lead to more stocks being assessed, with lower levels of uncertainty, thereby increasing yields and the overall sustainability of fisheries. This success would likely increase the amount of resources available for fishery manage-ment. Moreover, improving the scientific basis for fisheries management could reduce some other cost components of fisheries management, such as litigation and compensation provided when fishery failures occur.

The federal marine fisheries man-agement system in the United States is substantially underfunded to run the processes defined in the Magnuson-Stevens Act and reauthorized in 2007. For example, all investments in fisheries science (both traditional and ecosystem-oriented) total approximately $400 million per year (including all marine states’ investments). This level of support is measured against a $4 billion annual fishery (first sale value) contributing over $60 billion annually to the U.S. economy (NOAA 2008c). Fisheries management is inherently information-intensive, and the nature of questions being asked now and in the future will require even more timely and more spatially-explicit information to answer. The President and Congress have called for substantially greater fisheries investments in their 2009 budgets to address these gaps, including additional support for single-species fishery stock

assessments. We ought to be investing to reduce uncertainty in stock status, expanding the numbers of species for which information is available, and mak-ing implementation of regulations more predictable, not using “uncertainty” as a red herring diversion to undermine the foundation upon which science-based fishery decision making is built.

tHe aUtHors resPoNd:

We wholeheartedly agree with Murawski et al. that funding and support for fisheries management are much too low relative to the economic and social importance of the resource. We also agree that fishery management would be improved by allocating more resources to effective stock assessments. Of par-ticular concern is the fact that nearly half of the commercially important stocks in the United States do not have adequate population assessments, as pointed out by Murawski et al. An even smaller percent-age of important stocks are assessed in developing countries, making this problem even more pervasive on the global scale than in the United States (Johannes 1998). However, we do not see our article as being at odds with this line of reasoning.

Our argument was that precisely because the overall funds available for management are relatively scarce, there are difficult trade-offs to face concern-ing the use of these resources. We wish that adequate funds were available to do high-quality assessments on all important stocks, but are not optimistic that this will be case, at least in the near term. If all commercially important stocks in the United States cannot be regularly assessed using state-of-the-art methods, is it better to conduct more expensive assessments

on few stocks, or less expensive assess-ments on all stocks? How do you decide? In our view, the letter from Murawski et al. fails to address these points. They do not argue that stock assessments are more important than other management activities, but rather that stock assessments are underfunded. We do not disagree. We simply add that given budget constraints, the value of stock assessments should be measured relative to the value of other means of increasing the likelihood of successful fisheries management. Often times, the funding of stock assessments will be the most important use of manage-ment resources. Other times, it may not be. We urge managers and researchers to consider the potential tradeoffs that exist in their systems, and encourage continued dialogue on the subject.

First, I commend Jelks et al. (2008) for writing a very timely and critically impor-tant article that shows a very disturbing pattern in the status of fish species since Miller et al. (1989) and Williams et al. (1989). Given the actions and inactions of the responsible North American federal and state/provincial agencies over the past eight years, I encourage the AFS leader-ship to forward Jelks et al. (2008) to the responsible agencies in Canada, the United States, and Mexico. A letter should be included urging formal quantitative fish status evaluations and proactive conserva-tion measures beginning in 2009, and offering the assistance of AFS in doing so.

Nonetheless, I have two concerns with Jelks et al. (2008): (1) the use of hydrologic units as ecoregions, and (2) the omission of economic and population growth as root causes of fish imperilments.

There is growing evidence that eco-nomic and population growth are major drivers of fish and fisheries imperilment (Miller and Czech 2005; Rose 2005; Hyatt et al. 2007; Leprieur et al. 2008). I encour-age all authors concerned with landscape-scale species imperilment patterns to relate changes in species status to landscape-scale changes in gross domestic product and human population growth. It is high time that we aid policy makers in seeing the associations of our growth policies with habitat alteration, alien invasive species, and fish species extirpations. If we ignore the root causes of fish and fishery losses (as well as climate change), we cannot take steps to correct them, and instead we will only be recording those declines.

Hydrological units (HUs) are not ecore-gions, despite the contention of Jelks et al. (2008), Abell et al. (2000, 2008), and Maxwell et al. (1995). HUs are simply similar-sized map polygons that are river basins or catchments less than half the time (Omernik 2003). Ecoregions (ecologi-cal regions) are distinctive areas resulting from combined similarities in the mosaic of terrestrial, aquatic, abiotic, and biotic ecosystem components with humans being considered as part of the biota. Characteristics typically used to define these regions include physiography, geol-

ogy, soil, vegetation, climate, land use, hydrology, and occasionally fauna (Wiken 1986). Because they are drainage based and large scale, the HUs depicted in Jelks et al. (2008) merge mountain and plains ichthyofaunas wherever the HUs head in mountains. For example, in Jelks et al. (2008), region 7 includes fish faunas of the Cascades, northern Rockies, Willamette Valley, and Northern Basin and Range. Regions 58 and 62 include the fish faunas of the southern Appalachians, Piedmont, and Coastal Plains. Landscape classifica-tions have limited capacity to explain pat-terns in fish species distributions (Hawkins et al. 2000; Herlihy et al. 2006). However, individual zones (upper, middle, lower) predicted fish species richness better than complete basins in both the northwest (McGarvey and Hughes 2008) and south-east (McGarvey and Ward 2008) United States. Therefore, I recommend that future syntheses of this sort incorporate basin, ecoregion, and river size information to better clarify geographic patterns and aid resource managers.

tHe aUtHors resPoNd:

Hughes makes several valid points about our article (Jelks et al. 2008). The primary objective of the article was to update the list of imperiled freshwater and diadromous fishes following criteria established by previous endangered species committees (Deacon et al. 1979; Williams et al. 1989), and secondly to analyze changes since the 1989 list. We focused on presenting data using natural boundaries, unlike previous lists, which used political boundaries.

The authors agree that the use (and abuse) of land and water resources by humans is the primary cause of fish and fisheries imperilment. Of the five criteria used for listing in the article, four are directly attributed to human actions. It is plausible that a positive correlation exists between density of humans and fish imperilment. Although many of the listed taxa live in rural areas with low numbers of humans, changes in habitats and introduc-

tions of nonindigenous species can and do occur there. Human population growth and economic development are not mutually exclusive with the protection or even recov-ery of imperiled species. Indeed, humans are key to conserving imperiled biotas. Unfortunately, the pervasive trend for fishes in North America and globally is toward increasing imperilment which may lead to future extinctions. Clearly an evaluation of how population growth and economic policies promote risk for imperiled species is needed. However, that was not an objec-tive of our research and is far beyond the scope or intent of this study.

The suggestion that hydrologic units are discrete from ecoregions is a matter of semantics, scale, and preference. There are many different categorization schemes used to divide the biosphere into units, and each has advantages and disadvantages. Our use of the term “freshwater ecoregion” follows the definition from the World Wildlife Fund and The Nature Conservancy as “…a large area encompassing one or more freshwater systems that contains a distinct assemblage of natural freshwater communities and spe-cies. The freshwater species, dynamics, and environmental conditions within a given ecoregion are more similar to each other than to those of surrounding ecoregions and together form a conservation unit” (Abell et al. 2008; see www.worldwildlife.org/science/ecoregions/freshwater.html and www.feow.org).

The 80 freshwater ecoregions across North America used in our article are part of a larger network of 426 ecore-gions worldwide “…whose boundaries generally—though not always—correspond with those of watersheds” (also occasion-ally termed “drainage basins” or “catch-ments”; Abell et al. 2008). Ecoregions typically consist of a single river drainage or groups of adjacent ones, or sub-com-ponents, and therefore reflect intrinsic zoogeographic patterns of faunal similarity and endemism (Hocutt and Wiley 1986). Within individual ecoregions there usually are fish assemblage differences between upstream and downstream areas. In part, the freshwater ecoregion concept was developed because patterns of freshwater biodiversity are divergent from terrestrial patterns (Olsen and Dinerstein 2002). Conservation assessments and priorities for implementing protection and recovery strat-egies should appropriately be directed at relevant ecological and hydrological scales. In practice, most conservation efforts are

based on geopolitical boundaries (hence our website http://fisc.er.usgs.gov/afs/ pro-vides state and province data).

For our purposes of analysis and graphical display of imperilment across this large area, the 80 units termed freshwa-ter ecoregions were quite adequate. We did not need a finer scale of resolution to analyze the status of fishes, and patterns of endemism were largely captured using the drainages or groups of drainages. We hope our article will encourage the development and sharing of data sets relevant to fishes so that further analyses of basin, ecoregions of various definitions, river morphology, human population, resource use patterns, and other variables are possible. We are pleased by Hughes’ interest, and that of many others, and hope our article height-ens interest in conservation of aquatic biodiversity and responsible use of natural resources. —H. L.

resOLutiON ON the DeVeLOPmeNt OF iNstream FLOW PrOGrams

WHEREAS, the mission of local governing fish and wildlife agencies is to conserve, protect, restore, enhance and manage fish and wild-life resources and their habitats for current and future use, benefit, and enjoyment by state residents and visitors, and;

WHEREAS, the mission of local governing environmental protection agencies is to conserve, manage and provide for maximum public benefit of the natural resources, and;

WHEREAS, these mission statements are consistent with the Public Trust Doctrine, which requires that navigable waters, tide lands, and fish and wildlife resources be managed for the benefit of the citizens to ensure long-term sustainability so as to prevent or mini-mize harm to these resources, whenever possible, and;

WHEREAS, in some cases the local governing fish and wildlife agency does not have the regulatory authority to issue water use permits nor the ability to coordinate with and effectively influence the permitting decisions of the local governing environmental agency regarding water use, and;

WHEREAS, it is necessary to ensure that sufficient instream flow remains for fish and wildlife resources and outdoor recreational pursuits, and;

WHEREAS, the natural flow regime of streams and rivers is inherently variable and this variability is critical to natural ecosystem function and native biodiversity in streams and their associated riparian areas and floodplains, and;

WHEREAS, since some local governing resource agencies currently recommend instream flows that are a single flow value (e.g., 7Q10) to accommodate instream habitat needs for aquatic life, which is scientifically unjustifiable and which is typically less than the aver-age natural flow of the stream, and fails to reflect flow variability and cannot meet the habitat needs for all species nor maintain healthy fisheries,

WHEREAS, the American Fisheries Society has adopted and published Policy Statement #9—Effects of Altered Stream Flows on Fishery Resources (Revised)—which states “The concept of ‘minimum flows’ and other low flow standards based on statistical records instead of biology (whereby it is assumed that needs of stream fishes can be met as long as some water remains) are seriously outdated,” therefore be it

RESOLVED, the American Fisheries Society, assembled at its Annual Meeting on this 19th day of August in the year 2008 at Ottawa,

Ontario, urges the local governing and provincial fish and wildlife and the local governing and provincial environmental protec-tion agencies in North America to commit the necessary staff and financial resources to the development of instream flow protection programs that contain all the elements listed below:

• Useaninterdisciplinaryapproachtoconductinstreamflowstudiesthatevaluateandprescribeinstreamflowneedsinterms of hydrology, biology, geomorphology, water quality and connectivity. The spatial scope of instream flow studies should encompass the river channel, the riparian corridor and floodplain systems including connected groundwater.

• Withrespectandinconformitytoallexistingstate,federalandprovinciallaws,mandatesandregulations,thelocalgovern-ing fish and wildlife agency should exercise the primary authority for determining the appropriate instream flow necessary to restore, manage, protect and enhance fish and wildlife resources and habitats either directly—if it has that authority—or through a formalized process to coordinate such recommendations with and effectively influence the permitting decisions of the appropriate governing environmental agency which has the final authority for setting instream flows.

• Commitappropriatefiscalandhumanresourcestomaintainorrestoreflowsthatreflectthenaturalseasonalflowpatternin terms of intra-annual factors (magnitude, duration, timing, and rate of change) and inter-annual variability (frequency) to maintain or restore the natural ecological function of riverine resources.

• Incorporate public input into the decision-making process through direct efforts to inform the public regarding (a) how instream flows are administered and the benefits they provide, (b) the opportunities and limitations afforded by local governing and federal laws and policies for each, and (c) ways they can effectively participate in instream flow decision-makingprocessesandissues.

following the Western division/Oregon Chapter annual meeting in May 2008, restoration practitioners and fisheries biologists were treated to a workshop packed with presentations by leading experts in the field of stream restoration. Titled “Integrating Practical Approaches,” the workshop empha-sized the need to restore connectivity and enhance natural processes in order to accelerate recovery of dwindling fish resources and ensure long-term benefits. Sessions featured new and emerging scientific perspectives, as well as specific design recommendations for large wood and fish passage projects.

Expensive lessons learned from the past are critically important to share—these include failure of in-stream struc-tures, monitoring of poorly designed projects, death of riparian vegetation, unanticipated offsite flooding, or fish kills in spite of stream habitat improve-ments. Collecting baseline data provides an understanding of the processes dominating the landscape, enabling appropriate design, and also allowing for follow-up monitoring, which informs restoration science and stream system modeling.

Workshop participants learned about the evolution of salmon and the long history of poorly enforced stream protection policies. History is the fifth “H” described by Professor david

montgomery, University of Washington author of the books King of Fish and Dirt. The other major categories of impacts on salmon he described are the 4 Hs: harvest, hydropower, hatcheries, and habitat, the latter being the factor most widely addressed by restoration professionals. Mapping the habitat of the Puget Sound area demonstrates that the 90% decline in fish populations is associated with an accumulated habitat reduction of the same degree, including widespread loss of side channels and valley bottom wetlands. Montgomery contends that ignoring future devel-opment and associated storm water impacts, in the context of restoration plans, is inconsistent with ecosystem goals and salmon survival. Instead, he offers strategies for accommodat-ing human population growth while giving salmon a chance. To address the basic problems, people can recreate forested river corridors that reconnect lowland and upland streams. To reduce impacts of urbanization, low impact development can promote recharge and minimize impervious surfaces through design, bio-swale catchment basins, and installation of pervious pavement.

The challenges of urban stream rehabilitation also include the expan-sion of subdivisions and derek booth, Stillwater Sciences Inc. and University of Washington, predicts that there is an urban stream “coming to a logging area near you.” In the new science of eco-hydrology, biological changes are linked to the responses of streams to urbanization. The changes in stream flow have a huge impact and are hard to address without long-term watershed scale efforts. However, Booth noted that community stewardship can help guar-antee maintenance and raise awareness. Short-term local actions can contribute to overall efforts, including riparian planting, water quality protection, low-

impact development, and preventing further impacts on valuable habitat.

Farmers, ranchers, and woodland owners can also contribute to protect-ing and restoring aquatic habitat. dave buchanan shared the practices and principles that led to him obtaining Salmon Safe certification (a free ser-vice) for Tyee Cellars Wine. He received U.S. Department of Agriculture (USDA) Wetland Reserve Program cost-share funding from the Natural Resources Conservation Service for riparian tree planting, along with advice and minimal paperwork.

Climate change implies that baseline conditions are no longer the static, “no action” alternative. According to Colin thorne, University of Nottingham, UK, the past is no longer the key to the future, meaning that the concept of a reference reach may no longer be usable—ecological surprises are to be expected. Responses are uncertain and unpredictable, making monitoring all the more essential. To account for climate change, Thorne advised that more room is needed for stream channel adjustments and higher peak flows. This would include measures to widen riparian corridors, remove artificial con-straints, and design culverts for larger flows.

Rebuilding watershed resilience and restoring stream process were themes common throughout the workshop. Understanding which landscape, climate, and watershed and stream-scale variables are dominating a system, over space and time, guides the basis for projects that will be self-sustaining. Janine Castro, U.S. Fish and Wildlife Service and Portland State University, warned that projects designed outside the natural range of stream process variables can lead to habitat degrada-tion. “It is imperative that designers of stream restoration projects understand

the dominant stream processes, and the relative magnitude between processes, before they settle on a particular channel form.” Several case studies reinforced this message, indicating that a signifi-cant number of restoration projects have failed. Stream processes are affected by many factors, including flow, sediment delivery, vegetation dynamics, and urbanization.

A thorough understanding of the watershed system being rehabilitated reveals the various influences on the factors one might measure. Based on an extensive survey, Leslie reid, USDA Forest Service, Pacific Southwest Range and Experiment Station, Arcata, California, outlined the top 10 reasons monitoring projects go wrong, and pro-vided suggestions on how to avoid the pitfalls. A well-thought out study design and an analysis plan can also improve the cost-effectiveness of project moni-toring. Reid promoted a common rec-ommendation—that a multidisciplinary team of experts review the project—and for monitoring, a statistician is essential. She demonstrated the use of flow charts to help monitoring design and plan-ning. Several presentations displayed the complexities of stream restoration topics with flow charts, which help illustrate the intricacies and interconnectedness of the physical, biological, cultural, social, and political components comprising restoration.

“Thinking like a network” is how Jason dunham, u.s. Geological survey, Forest and Rangeland Ecosystem Science Center, Corvallis, Oregon, frames the current science of river ecosystems and how stream network dynamics affect the resilience of fish. An interdisciplin-ary team can integrate perspectives of physical processes and biological responses. Dunham emphasized the need to address multiple scales, as well

as the probability of location-based species occurrence. He presented the concept of “patches” as improving on less informative and more homogeneous frameworks for understanding water-sheds (hydrologic units). Landscape-scale wildfires were the examples of disturbance used for Dunham’s research where he found that resilience depends on the existence of certain factors prior to the catastrophic fires.

brian bair, usda forest service, Washington state, described how his interdisciplinary team strives to provide complex habitat for multiple species and life stages, and a full range of flows within a flow regime. This group of scientists design remediation projects so they mimic native aquatic species adaptation to natural flow regimes. They consider using the full extent of available habitat, and where resources are limited, he recommended treating floodplains first.

In the quest to restore natural stream processes and habitats, the use of large wood structure placement has increased in restoration projects over the last 15 years. engineer scott wright, River Design Group, Inc., illustrated the drawbacks of many of these projects, the engineering design parameters to consider, as well as essential limiting factors for fish habitat. He highlighted the need to understand the natural occurrence and different functions of large wood in river processes, in order to ensure sustainable large wood place-ment that provides long-term benefit to aquatic resources.

engineer rob sampson, usda Natural resources conservation service, Idaho, presented fish passage proj-ect design configurations, modeling techniques, and hydraulic parameters. He cited several examples of natural and human-made discontinuities in

stream profile—including weirs, con-structed riffles, ramps, and step-pools. His goal is to establish a stable geom-etry that addresses the discontinuity. He learns from natural “knick point” hydraulics and his review of failing projects revealed that they were often designed “ignoring the laws of physics.” Depending on the width and slope of a stream, different types of structures are needed. For example, “ramps” may be appropriate for low-gradient, wide streams, while step-pool structures are more appropriate in high-gradient, nar-row channels.

Phillip williams and Associates (PWA) examine the whole system in designing tidal restoration projects. Dr. Williams reiterated that rigorous plan-ning and design is essential, including a sediment budget, evaluation of vegeta-tion dynamics, monitoring and adaptive management, and simulation models based on empirical hydrologic data. He indicated that marshes are relatively resilient ecosystems when it comes to pollution (e.g., oil spills), but that exotic species, which change the morphology of marsh interface areas and sediment dynamics, have a larger and more long-term effect. Williams also favors restor-ing natural processes and connectivity, rather than extensive, and expensive, grading—but the recovery time for natu-ral evolution can take decades.

Aquatic nuisance species are the focus of Paul Heimowitz, U.S. Fish and Wildlife Service, Region 1, because they are a very significant threat to native ecosystems. He advocates that anyone working in aquatic restoration help with awareness-building, early detection, and spread-prevention advocacy. He shared the stories of invasive freshwater mussels that highlight the problems of these “habitat snatchers”: they arrive

iNtrodUCtioN

Student involvement in the Minnesota Chapter (MNAFS) has been decreasing since 2004 (Figure 1). The MNAFS Long Range Plan calls for increased student participation in both the Chapter and the parent Society. This responsibility is listed specifi-cally under the duties of the Student Committee chair of the Chapter. Participation of undergraduate students is of particular interest, as there was only one oral presentation by an under-graduate at the 2008 MNAFS annual meeting. Furthermore, beginning one’s AFS membership as an under-graduate can increase preparedness for future graduate school or career opportunities.

In an effort to increase undergradu-ate student participation in MNAFS, the Chapter initiated the Institution Representative Program (IRP). The IRP connects MNafs to Minnesota univer-sity and college faculty and students. It

also encourages meeting attendance, promotes knowledge and awareness of fisheries-related issues and research, and provides an informative and sup-portive social network (Figure 2). The objectives of this article are to describe this unique program in detail, explain how this program benefits students and AFS, and discuss the successes of this program thus far and how success will be measured in the future.

how does the irP work?

The IRP program is headed by the Student Committee chair (SCC) of the MNAFS. The SCC is an active member of the Executive Committee (EXCOM) of MNAFS and is well acquainted with “hot topics” and issues of the MNAFS and the parent Society. The SCC is also responsible for establishing a faculty contact at each college or university that offers degrees or classes in fisher-ies and aquatic sciences. Institutions with social science programs that cover human dimensions in fisheries and

wildlife may also be considered. The sole responsibility of the faculty contact is to serve as an ambassador of AFS for students, enticing and enrolling inter-ested students into the Society.

The second step of the process involves recruiting a Student Committee institution representative (SCIR). There are two methods suggested for recruiting SCIRs: (1) enrolling students through the faculty contact at each university or college, and (2) directly contacting interested students (e.g., during a state Chapter AFS meeting). Students interested in becoming SCIRs then submit applications to the current SCC. The most qualified applicant from each college or university is selected to represent his or her institution on the MNAFS Student Committee.

The selection process for SCIRs is fairly rigorous. Numerous categories are considered during the selection process. The application asks undergrads to list their GPA, major and minor, and related coursework. Space is provided for

discussing any other relevant accom-plishments. Finally, a one-page paper is requested to determine the applicants’ writing skills and to provide applicants an opportunity to express their level of interest in aquatic sciences. Preference is given to students taking coursework or seeking a degree in fisheries or another aquatic science. Students with social science majors who are interested in working with natural resources issues are also eligible. All applicants are highly encouraged to join MNAFS and the parent Society.

Once selected to join, SCIRs are provided regular and current informa-tion on issues within afs. currently, training packages for SCIRs include articles that cover “hot topics” and background information discussed by the MNAFS EXCOM. Some articles pro-vide good examples of how opinions of various constituent groups vary on the same issue. The primary responsibility of each SCIR is to initiate discussions on their own campus that focus on similar topics. Existing MNAFS SCIRs are utilizing student organizations as the primary means of facilitating important discussions. Discussions should have three important results: (1) stimulate critical thinking, (2) increase aware-ness of issues in fisheries and aquatic sciences, and (3) develop leadership skills. Through these types of discus-sions, SCIRs will be better equipped to tackle potential problems by familiariz-ing themselves with fisheries issues they may address throughout their academic and professional careers.

Several other responsibilities accompany acceptance into the IRP. Membership in MNAFS is required. Membership in MNAFS is free for all students, but the SCIRs are also encouraged to join the parent Society. Attending the MNAFS annual meeting

is highly recommended, and each SCIR is encouraged to present any research they have completed while attending. Finally, each SCIR should assist in the recruitment of their replacement; this facilitates smooth transitions between representatives and ensures the pro-gram continues at each institution.

beNeFits oF tHe irP

The establishment of the IRP benefits students and AFS. First and foremost, students selected as SCIRs will strengthen their graduate school applications and resumes. Only one student per institution will be selected for this position, which is a distinguish-ing honor. Secondly, SCIRs have the opportunity to learn more about the impact professional societies such as AFS may have on their educational and professional careers. Finally, all students become more aware of fisheries issues either by serving as a SCIR or interact-ing with their local scIr.

There are no monetary costs associ-ated with beginning this program. Time investments by the SCC, the EXCOM of MNAFS, and other willing members of AFS are all that is required to initiate and more importantly sustain this pro-gram. The IRP was originally created to increase undergraduate participation at the state level; however, students may be more likely to participate in AFS at the Division and Society levels as well. The parent Society’s outreach mission can be accomplished through imple-menting IRPs or similar programs.

measUres oF sUCCess

Although the IRP is fairly new, some measures of its effectiveness have already been demonstrated. The Minnesota Chapter’s Student Committee has experienced a 600% increase in size. At the MNAFS

annual meeting in March 2008, the Scholarship Committee announced they had received a record number of applicants for Chapter scholarships. Further, female participation among the membership of the Student Committee of MNAFS had also increased. Thus far, the IRP program appears to be off to a strong start.

Future success of the IRP will be measured by six metrics. The first mea-sure of success will be the size of the Chapter’s Student Committee. Student membership is an obvious, yet impor-tant measure of success. As of the last MNAFS Annual Meeting, student membership stands at 27 individu-als. The count after the next annual meeting will reflect the effect of the IRP on student membership. Three other measures of success will also take time to analyze. The number of applications for student scholarships and travel scholarships will be recorded over time. Increases in the number of students registering and in the number of oral and poster presentations by students at the annual meeting will also be mea-sures of success.

CoNCLUsioN

The new IRP implemented by the MNAFS Student Committee is a way to get undergraduate students more involved in AFS at all levels. We believe this program could be established and successfully implemented for all Chapters to promote increased mem-bership, enhance member involve-ment, and increased visibility among the general public and fisheries-related professionals alike. We believe that this top-down approach is a first step to achieving a greater unity between AFS Subunits that is needed to pursue the Society’s overall goals.

ObITUARy: RoBERT DAVID BISHoP

Robert David “Dave” Bishop, 74, father of Tennessee’s striped bass program, passed away in September 2008 after a coura-geous battle with cancer. As a youth he loved to hunt and fish, spending many hours and days in the field. He was a member of the last graduating class of the old Knoxville High School and enjoyed attending their weekly reunion breakfasts after his retirement.

From 1951–1955 he served in the U.S. Navy as a member of the Blimp Service out of Jacksonville, Florida. He became infatuated with the fish he saw in the ocean while patrolling. He later told his wife Sue that this was the first time in his life that he had all he wanted to eat. After the Navy, Bishop entered the University of Tennessee. He began his academic career as an engineering student but later changed his major to biology. In

1958 and 1959 he worked as a part-time aide for the Tennessee Game and Fish Commission. He was hired as a fisheries biologist in 1960.

During his early career he worked with population stud-ies and the muskellunge program. He became interested in the newly developing freshwater striped bass program which began in South Carolina. He is now recognized as the father of Tennessee’s striped bass program and successfully crossed striped bass and white bass in 1964–1965, becoming the father of the hybrid along with Bob Stevens of South Carolina. The scientific papers on the hybridization of striped bass x white bass that Bishop presented in 1966–1967 are still being used today.

In 1972, he spawned the first striped bass in Tennessee and in 1974 discovered and developed the tank spawning method for striped bass which is used by several states today. In Tennessee alone, over 375 million striped bass have been spawned using his techniques. Also in 1974 he was promoted to assistant regional manager in Region IV for the newly created Tennessee Wildlife Resources Agency.

In 1988, Bishop was instrumental in procuring a long-term lease with the Tennessee Valley Authority to use Doakes Pond to rear fish for Norris Lake. This pond was built by the Civilian Conservation Corp and had much historic value. Bishop designed and developed a harvest system which put the pond

back into operation and saved it from destruction. As a result, thousands of fish have been stocked into Norris Lake.

In 1996, Bishop was honored by being enshrined into the National Fish Culture Hall of Fame in Spearfish, South Dakota for his work with striped bass and hybrids. This honor placed him among the elite fisheries scientists of the last century. In 1997, Bishop retired from the Tennessee Wildlife Resources Agency after 43 years of service. After retirement, he enjoyed farming and spending time with friends and family.

The sportsmen of the state of Tennessee owe Bishop a great deal of gratitude for his pioneering work done with striped bass and hybrids. He truly was the sportsman’s friend.

He will be missed dearly but never forgotten.

—Mike Smith

without their natural predators, out-compete and sometimes smother native species, reproduce extremely well, and are associated with human develop-ment and related transport vectors. Heimowitz does not see eradication as a realistic option except when detected early, and he discussed how biologi-cal controls can backfire. While some regions have not yet been affected by invasive mussel species, expansion is inevitable, with invasions of additional species on the horizon. Practical steps that can be taken include: education and outreach, using identification cards that Heimowitz distributed, instituting more check points and cleaning stations for boats and other vectors, enforcing existing laws, and instituting stronger laws.

Removing barriers to habitat is also a priority fish recovery strategy. Instead of Portland General Electric provid-ing expensive fish passage facilities at the Marmot Dam in order to re-license the hydropower operation, “fluvial opportunists” from many agencies collaborated to amass the necessary resources to remove the Marmot Dam.

gordon grant, usda forest service, Pacific Northwest Research Station, and Oregon State University, described this unmatched research opportunity on the Sandy River watershed draining from Mount Hood. A video produced by Oregon Public Broadcasting, “A River Runs Free,” can be found at www.opb.org/programs/ofg/videos/view/73-Mar-mot-Dam. Numerical and physical mod-els helped to predict sediment release, but there were unexpected effects. The actual event, along with ongoing moni-toring, provides valuable information for future dam removal projects designed to restore endangered fish runs.

On the Elwha River, two dam removal projects are planned for 2012, which will be the largest dams ever removed. All seven anadromous Pacific salmonid spe-cies have been isolated from their habitat for 95 years. Their pending access to 130 kilometers (80 miles) of nearly pristine habitat is complicated by the presence of dominant coho salmon hatchery fish and an anticipated increase in competi-tion with the recovery of native fish. sam brenkman, Olympic National Park, Washington, provided an overview of

fisheries monitoring and research projects underway. Understanding existing condi-tions will enable successful fish rescue plans during dam removal. Evaluating future responses of Pacific salmonids after removal is important, as the interac-tions among multiple species will vary throughout the watershed, and natural migration barriers will limit the extent of recolonization in tributaries.

Restoring natural process integrity, connectivity, and channel configurations that can withstand responses to climate change are important to enhancing the resilience of stream systems. Stream restoration is complex; the intricacies and interconnectedness of the physical, biological, cultural, social, and political components comprising restoration make it all the more challenging to practice effectively. Self-sustaining projects are likely those planned by an interdisci-plinary team with a whole-watershed, all-species perspective. One participant suggested that the workshop curricu-lum be required reading for all stream restoration stakeholders. This was the fourth workshop of its kind sponsored in Oregon by AFS since 1993.

the use of the best available science, the committee will seek collaborative solutions to improve the management of the endangered species programs at the U.S. Fish and Wildlife Service and National Marine fisheries service. by encouraging the issuance of appropri-ate guidance, regulations, and federal/non-federal partnerships, the commit-tee will play a leadership role in endan-gered species conservation.

Ensuring a Legacy of Abundant Fish and WildlifeThe U.S. public inherited from our forebears an abundance of diverse and healthy populations of fish and wildlife. According to the U.S. Fish and Wildlife Service’s “2006 National Survey of Fishing, Hunting and Wildlife Related Recreation,” an estimated 71 million Americans spent over $45 billion on some form of fish and wildlife recre-ation in that year. Yet, several factors, notably habitat loss and fragmenta-

tion, invasive species, inadequate water quality and availability, and the illegal trade in wildlife and wildlife products threaten our wildlife legacy, not only in the United States but also around the globe. Energies must be directed to develop and implement new poli-cies and programs that improve the management of our fish and wildlife species, provide habitat protections they will need to adapt and thrive in the midst of a changing climate, pro-tect against illegal trade, and promote international conservation efforts.

Achieving the True Promise of Multiple Use

In outlining the mission for the Bureau of Land Management (BLM), the Federal Land Policy and Management Act of 1976 (FLPMA) stated the following: The public lands [shall] be managed in a manner that will protect the quality of scientific, scenic, historical, ecological,

environmental, air and atmospheric, water resource, and archeological values; that, where appropriate, will preserve and protect certain public lands in their natural condition; that will provide food and habitat for fish and wildlife and domestic animals; and that will provide for outdoor recreation and human occupancy and use. A new dedication to realizing the goals of this multiple-use mandate is required because the promise of FLPMA has never been fully realized. Public lands are diverse enough to accommodate the development of plentiful energy resources, where appropriate, along with wilderness designations, conser-vation of habitat for wild horses and burros, grazing, archeological preserva-tion, and the many other goals set out in FLPMA. Enactment of the National Landscape Conservation System within BLM is an important first step in the process of achieving these long-delayed goals.

AFS ANNUAL MEETINg:

3rd CALL FOR PAPERS

GEnERAL InFORmAtIOn

Aquatic resource professionals are invited to submit symposia proposals and abstracts for papers in a range of topics and disciplines. Participation by scientists at all levels and backgrounds, especially students, is encouraged.

The scientific program includes two types of sessions: Symposia (oral and poster presentations that focus on a single topic) and Contributed Papers (oral and poster presentations on any relevant topic).

Oral presentations are limited to 20 minutes (15 minutes for presentation plus 5 minutes for speaker introduction and questions). All oral presenters are expected to deliver PowerPoint presentations. Presenters must bring their PowerPoint file to the meeting on CD or USB flash memory stick by 7 p.m. the evening before their presentation. Laptop computers and LCD projectors will be provided and technicians will be available to help.

Traditionally, symposia have been dominated by oral presentations and sometimes supplemented by posters. The Nashville ‘09 Program Committee is considering following the example set at the Ottawa ‘08 meeting and allowing “Speed Presentations” coupled with posters to shorten the time required for symposia. This new format elevates the profile of symposium posters through a “speed presentation subsession” that provides a time slot for short (i.e., 3 minute) oral presentations, followed by dedicated viewing of symposium posters. Look for more details in upcoming Calls for Papers on this exciting new way to transfer information and foster communication among symposia participants.

SymPOSIum The Program Committee invites proposals for symposia. Topics must be

of general interest to AFS members. Topics related to the meeting theme will receive priority. Symposium organizers are responsible for recruiting presenters, soliciting their abstracts, and directing them to submit their abstracts through the AFS online abstract submission form. A symposium should include a minimum of 10 presentations and we encourage organizers to limit their requests to one-day symposia (about 20 oral presentations). Regular oral presentations are limited to 20 minutes, but double time slots (i.e., 40 minutes) may be offered to keynote speakers. Symposia with less than 15 or more than 20 presentations are strongly discouraged.

Symposium proposals must be submitted by 9 January 2009 via e-mail to Mark Bevelhimer ([email protected]) with the proposal attached in the correct format in MS Word or WordPerfect; please contact Mark Bevelhimer if you do not receive confirmation by January 16. The Program Committee will review all symposium proposals and notify organizers of acceptance or refusal by 6 February 2009. If accepted, organizers must submit a complete list of all confirmed presentations and titles by 27 February 2009. Symposium abstracts (in the same format as contributed abstracts; see next

page) are due by 6 March 2009.

tROPHy FISHInG

Tennessee offers diverse fishing opportunities, but most people don’t know that Tennessee also boasts the world record walleye (25 lbs.) and smallmouth bass (11.9 lbs.). Tennessee also claims the world records for bighead carp (90 lbs.), yellow bass (2.6 lbs.), and freshwater drum (54.5 lbs.). Tennessee’s state record striped bass (a whopping 65.4 pounder) is the second largest inland striped bass ever caught!

StudEnt SymPOSIum

The AFS Education section will once again be sponsoring a Student Symposium. Students interested in being chosen to participate and compete for Best Student Paper and Best Student Poster will have the opportunity to indicate that during the abstract submission process. We urge interested students to read about the process before going online to submit an abstract: Sutton, T. M., D. L. Parrish, and J. R. Jackson. 2007. Time for a change: revision of the process for judging student presentations at the annual meeting. Fisheries 32(1):42-43. Please contact Jim Peterson (chair, Best Student Paper Committee; [email protected]) or Richard Fulford (Chair, Best Student Poster Committee; [email protected]) for additional information.

Students not participating in the Student Symposium will have the opportunity during the abstract submission process to indicate that they would like to receive written feedback on their presentations and posters. Feedback will be provided by volunteers and the process will also be directed by the AFS Education Section. Volunteers will have the opportunity to pick-up blank forms and drop-off completed forms at several locations around the meeting site. A copy of the evaluation form can be found on the Education Section webpage (July 2008 newsletter) at http://www.fisheries.org/units/education/newsletters/edsecnews_v29_1.pdf

pUbLICATIONS: Book REVIEW

bluegills: biology and behavior. By S. Spotte. AFS, Bethesda, Maryland. 2007. 214 pp.; $35 ($24.50 for AFS members) (paper); store.afsbooks.org/55054p.html.

With Bluegills: Biology and Behavior, Stephen Spotte offers up a treatise on everything one might want to know about this popular, nearly ubiquitous freshwater sunfish. Because the protagonist is a crit-ter already near and dear to my heart, I really wanted to like this book. So, when it arrived in my mailbox, I grabbed my pen and a coffee and, with much anticipation, sat down to read. At first glance, one can’t help but be impressed with the comprehensive coverage and level of detail this book provides about an interesting and unique little Lepomid. Through eight chapters, Spotte touches on all aspects of bluegill life history and ecology, beginning with move-ment, sensory percep-tion, and foraging (chapters 1–3), continu-ing through competition and predation (chapters 4–5), and finishing off with reproduction (chap-ter 6), development, growth, and mortality (chapter 7), and man-agement (chapter 8). In sum, the book covers 150 pages and refer-ences more than 500 citations (via 1,327 footnotes).

Therein, unfortu-nately, lies the first of many challenges. By the middle of the first chapter it becomes clear that the text is detailed

to near incomprehensibility. A paragraph on blue-gill movement begins, “The hydrodynamic vortices around a swimming fish resemble the dipole field of a submerged vibrating sphere in which pressure gradients cause fluid particles to fall off and acceler-ate away from the sides, disengaging with the cube of the distance and proportional to the volume of the moving object”—a sentence sure to cause collec-tive head scratching among most fishery scientists. The problem is most of the book is presented at that depth of detail. Indeed, just seven lines into the first chapter I read, “The starting vortex, or detached eddy, has a counter clockwise rotation (+K). The

bound vortex, or bound circulation, which has a clockwise (-K) rotation, remains attached until the starting vortex has been shed.” Suddenly doubting the quality of my public education, I handed the book to a colleague and asked him to read the first chapter. In 30 seconds, he was back with raised eyebrows, having read only the first page. His response: “Wow.” Truth be told, information this detailed would likely take a separate expert to review each chapter; even with broad and reasonably comprehen-sive training in ecology and physiology, I felt unqualified to review at least three of the eight chapters in the book.

In addition to depth of detail, the sheer volume of informa-tion presented cre-

Page 47: Fisheries · Fisheries • vol 33 no 11 • november 2008 • 531 Fisheries AmericAn Fisheries society • edITorIal / subscrIpTIoN / cIrculaTIoN offIces 5410 Grosvenor Lane, Suite

MyriaxFisheries • vol 33 no 11 • november 2008 • www.fisheries.org 575

ates additional issues. The first is that Spotte often so overwhelms the reader with specific details that general patterns are obscured. For example, so many site- and state-specific data on bluegill spawning peri-ods are presented that I suspect the uninformed reader would miss the simple point that bluegill typically exhibit a protracted spawning season that stretches through much of the spring and summer. Ironically, this problem works against him in just the opposite way; Spotte often presents extremely site-specific information as generalizable to the species as a whole. In his introduction to the final chapter, Spotte notes, “What we know is never certain because each lake is dynamic and possessed of unique vulnerabilities.” Unfortunately, he mostly fails to apply that admoni-tion to the previous seven chapters. The book would have benefited from more informed interpretation, to provide the reader with a clear picture of which studies are valid, supported, and generally applicable, and which are specific and anecdotal. Instead, it reads as a series of “facts” collected from a vast body of published literature (some widely cited and generally accepted, some not) and offered in boxcar fashion, one following the next. Some topics are covered com-pletely and competently, others really miss the mark (foraging and stunting are two, in particular, that come to mind). This leads to problems with organization and repetition, which are exacerbated by the construct of the chapters; much of the information is repeated within and among chapters, and necessary contextual-ization is often missing.

Perhaps the biggest obstacle for this book, however, is the lack of a clear audience. In his introduction, Spotte indicates that, “The text you are about to read is unconventional in both organization and content....Readers must be willing to undertake an intellectual challenge....” In this case, he’s right on the mark. The problem is, it’s just not clear to me who’s going to be up for that undertaking.

ATS takes fisheries research

to new depths and detection ranges.

To determine movement patterns and conduct stock assessment of Chinook Salmon on the Yukon and other Alaskan Rivers, researchers turned to ATS.

Very sensitive receiver/datalog-gers, in combination with uniquely coded fish transmitters, were de-signed by ATS to accurately detect fish movement and run timing in the deep and remote reaches of the rivers. Hourly data was re-layed via satellite to researchers and participating agencies.

On one project, researchers cap-tured 1,000 salmon at the mouth of the river and implanted a uniquely coded transmitter. The fish were then tracked as they pro-gressed upriver using 39 fixed data collection sites with satellite data transmission capability. The study also used ATS receivers equipped with on-board GPS for aerial sur-vey work.

With data capture rates as high as 98 percent, ATS coded transmit-ters and R4500 Receiver/Datalog-gers resulted in increased detec-tion ranges of up to 100 percent.

Tracking systems designed by ATS play a key role in aiding fisheries professionals conducting impor-tant research worldwide. To learn more about how our systems will benefit your next project, contact an ATS representative today.
